概要

原子核科学研究センター（CNS）では、重イオンを利用したテーマを中心に、核物理実

験・理論研究を広く推進している。この分野の次代を担う若手、特にアジアにおける人材の

育成を目的とした国際サマースクールを、以下の通り開催した。

開催期間 2012 年 8 月 29 日（水）～ 9 月 4 日（火）開催場所 CNS 和光分室、理化学研究所仁科ホール、

東京大学本郷キャンパス小柴ホール組織委員下浦享 (CNS 教授・校長）、大塚孝治 (CNS センター長)、

中務孝 (理研仁科センター)、酒井英行 (理研仁科センター)、櫻井博儀 (東大/理研仁科センター)、宇都野穣 (JAEA)、宇都宮弘章 (甲南大)、山口英斉 (CNS)、清水則孝 (CNS)、道正新一郎 (CNS)、郡司卓 (CNS)

本サマースクールは、2002 年に東京大学大学院理学系研究科国際交流計画の一環として

始まったスクールの 11 回目であり、国内外から 9 名の講師に講義をお願いした。第一原理

からの核構造の理解、基礎的な核反応理論と宇宙核物理における応用、特殊な不安定核の核

分光による原子核ハローや集団運動の研究、原子核散乱における「虹」などの興味深い現象、

少数系における三体力の重要性、原子核の巨大共鳴、荷電交換反応実験とその意義、QCDの相転移における新しい理解、核力におけるテンソル力の重要性、といった、最新の研究成

果に基づいた多岐にわたる講義が展開された。今年度も理学系研究科間接経費による国際交流計画からの援助により、国内外から参加し

た学生に補助を行う事ができた。最終的に参加者は 94 名（講師含む）を数えた。国外から

の参加者は、７カ国計 24 名(うち講師 4 名)であった。そのうちアジア(中国、韓国、ベトナ

ム)からの大学院生、ポスドクは計 18 名である。このように多くの学生がアジア地区から本

サマースクールに参加したことは、原子核科学研究センターが目指すアジア地域での研究拠

点形成に大きな役割を果たしたと言える。また、国内では、東京大学・理研を中心に 12 の

大学・研究機関からの参加があった。学内からは 30 名の大学院生およびポスドクが参加し、

第一線で活躍する講師陣による講義で、専門的知識を享受する事が出来た。本サマースクールでは、学生・ポスドクによる口頭発表およびポスター発表に十分な時間

を取っているのが一つの大きな特徴である。そのような「若手セッション」においては、活

発な議論が交わされ、国内外の学生が互いの研究テーマについて話し、交流を深め合う事が

出来た。英語による講演や質問が初めての学生も多々見受けられたが、国際会議に比べてリ

ラックスした雰囲気の中での研究成果の発表や討論は、若い学生にとって非常に良い経験と

なったはずである。

サマースクール感想文から

Dmitry Chernyak

Institute for Nuclear Research (KINR, Kyiv, Ukraine) Thanks to the 11th CNS International Summer School (CNSSS 2012) I was able to

expand and polish my knowledge of nuclear physics. Also this summer school gave me a good opportunity to present my current work of PhD study to a great audience. Moreover I was interested in Japanese culture, life and traditions for a long time, so CNSSS 2012 also allowed me to enjoy my stay in Japan. I want to thank lecturers for interesting and useful lectures, students for great

discussions, and of course organizational committee for their excellent work, constant support and making all this possible. In my humble opinion the greatest achievement of this summer school is that now I

know in which country I really want to obtain a postdoctoral position!

私は筑波大学大学院数理物質科学研究科博士後期課程１年の大学院生です。私は修士課程

１年次から毎年CNS Summer School に参加しており、今年で三度目の参加となりました。

私はこのSummer School に参加することを、毎年楽しみにしています。 Summer School の感想ということで、幾つか私の意見を述べたいと思います。先ず、私はこのSummer School の存在を、非常に有り難く感じています。というのも、こ

のCNS Summer School は、若手研究者、特に修士課程の学生にとっては数少ない英語で

の口頭及びポスター発表の機会であり、そして、英語で海外の同世代の学生や講師の方々と

議論を交わすことのできる機会であるからです。私の場合も、初めての英語口頭発表を昨年のCNS Summer School で経験し、その経験で

自信をつけ、別の国際会議での口頭発表へ望むことができました。また、CNS Summer School は、上述のような国際的な経験をできるだけでなく、最先端の研究を肌で感じるこ

Daid Kahl CNS, the University of Tokyo

It is always a pleasure to attend the CNS annual summer school. Fitting with the

tradition, exceptional quality lecturers traveled from near and far to instruct a diverse group of students. Although busy with my own thesis work, I attended a few sessions as well as the social events to network with new and old friends. I am pleased with the school's custom to provide dedicated oral and poster sessions for young researchers, because learning is not a passive activity. I would like to emphasize the importance of continued funding for one of the world's finest nuclear physics summer schools, in particular to assist in supporting the travel costs of students and young researchers from abroad. In the future, I hope the program structure could be modestly altered to strongly encourage if not force young people to ask more questions after each talk, which is about the only improvement that could be asked.

Sun Lijie China Institute of Atomic Energy

Thanks for the perfect preparation of the CNS Summer School Organizing Committee.

We have experienced a wonderful week in Japan. This is a pretty good opportunity for students in nuclear physics to broaden our horizon, enrich one's experience and get acquainted with other physicists. Among the summer school agenda, I think the poster session is an impressive part. We could discuss freely and I obtained much knowledge. In addition I also learned a lot from the RIBF tour and see the first-rate facilities on RIB in the world. In life, we were offered with very comfortable as well as modern lodging

- 13 -

and we can feel Japanese delicate life style and they are extremely polite. In summary, this summer school is a wonderful platform for physicists to exchange

ideas and to communicate with each other especially for young scientists. It is rather beneficial for academic exchange and cooperation. Thank you for your considerate service and please accept my sincere wishes for the 12th CNS Summer School in 2013.

Jia Wang SINAP (Shanghai)

First, I am glad to be able to participate in the 11th CNS Summer School at RIKEN,

the organizers' careful work offered us a lot of convenience, providing a detail map from the airport to RIKEN, arranging accommodation, setting out summer school schedule, which made us into the life of summer school without any difficulty. So I had a good time in the summer school. And, the teacher's lectures were very rich, so I had learned a lot. The organizer also

gave us students the opportunity to report, which not only lets us exercise but also allows us to communicate with more people. The interesting poster form promoted the exchange of the participants. And visiting the laboratory of RIBF impressed me. It is very neat and orderly. The equipment is very excellent, fully in line with world-class laboratory standards. I think there are a lot that we can learn. Lastly, I thank organizers giving us the opportunity to participate the summer school,

where I learned a lot, got a lot of exercises and also had a very good time.

Rin Yokoyama CNS, the University of Tokyo

I enjoyed listening to the wide variety of topics of the lectures. Most of them were

interesting for me somehow. As for the young student session, it was a good opportunity to know what other

students study, in order to have conversations with them especially the students from abroad. I felt glad that some people looked interested in my study in the poster session.

Li Ting Institute of High Energy Physics, Chinese Academy of Sciences

I’ve appreciated very much for your invitation and organization of CNSSS12. I spent

happy seven days studying and living there. The professors are top scholars in the field of nuclear physics and their lectures were about developments on it. Every lecture was wonderful though they were difficult for me to understand. It might be better that lectures were sorted in an order beginning with graphical ones. I wondered whether we could have a chance to communicate with other professors, for example, in the field of Imaging. The lectures were helpful for us students. Life in the campus was convenient though the consumption was high. In general, it was a wonderful summer school. I hope there will be more chance for me or others to join you.

Qibo Chen, Peking University

Although the 11th CNS International Summer School has been end, the good

impressions she leave me will not be end. In my personal opinion, this summer school is a very successful school. From the lecture aspect, the covered topics ranged from nuclear structure to nuclear reaction, from finite nuclei to nuclear matter. All of them are hot topics and attract

- 15 -

scientist’s many attentions in the nowadays. More important is that the invited lecturers are the excellent experts in these fields. They explained the profound things in a simple way and make it easier to understand for students. They answer the questions with lots of patients and passions. We had intent discussions and benefit a lot. From the organization aspect, the organizers have done a lot of things to make sure the summer school going smoothly. They helped us order the hotels. They organized the meeting room. They provide break food and drink for us. They held welcome and farewell parties. They gave many announcements which contained lots of information and helped us come up with the pave of the summer school. It seems as if all of this things are the responsibility of organizers and should be done by them, however, in my view, this are one indispensable part of the summer school. I would like to express my sincerely thankful to the organizers. From the student session, the summer school provides a platform for us students to introduce our work to others. It is a good chance for me to give the international talk before foreigners. I have benefited a lot under discussion with other students. All in all, CNSSS12 is a perfect summer school.

He Wanbing SINAP (Shanghai）

The organizers of the 11th CNS Summer School at RIKEN gave detailed guidance, so I

was able to participate in the summer school very smoothly. Organizers given very attentive prompt transportation from the airport to RIKEN, so I was able to be very smooth arrival residence at RIKEN, although this is the first time I went to Tokyo. The accommodation here is very good, clean and tidy. The RIKEN environment is very beautiful, the air is fresh. Summer school provides us with very good lectures, so I learned a lot. We are fortunate

to know many peers, and discussed some of the academic issues. All the teachers and students at the summer school are very friendly, and I admire that their work are very rigorous, interesting. I was impressed by the time to visit the laboratory of RIBF. It is very neat and orderly. Laboratory experiments are in very good condition. The equipment is very excellent, fully in line with world-class laboratory standards. The Sunday at summer school, we have a brief tour around the city of Tokyo. Tokyo is

very prosperous, in convenient and orderly. When we got lost, people gave us help very friendly. Very grateful to the organizers to provide us with such a perfect RIKEN trip, learned a

lot, and I left a good impression. I wish CNS summer school will be better and better!

Pilsoo Lee Chung-Ang Univ

I'm a master student in Korea, and this is my second time visit to CNS summer school. All lectures were very informative and exciting. In Korea, it is very hard to attend such

good lectures about nuclear physics because only a few professors give lectures of that topic to students. And most lectures dealt up-to-date issues. Especially, I was extremely interested in

"gamma ray spectroscopy of exotic nuclei" by Prof. G. de France. RIBF tour was also very interesting. Guidance of Prof. Uesaka was very helpful to understand the purpose of each parts during the tour. But I felt something great was missing because most participants were Chinese. I

think it would be better to meet students from more various countries. And talks of some young scientists were terrible. It looks like some guys do not practice before they give talks in front of many people. Finally, a holiday during the period was very nice. Last year, the summer school was

held from Monday to Saturday in straight days, so it was somewhat tired, but that is not the case this year.

Tang Tsz Leung CNS, The University of Tokyo

This is my first time to attend the summer school. I feel it is intense and covered a lot

of topics. So the material is good. The only thing is, we don't have any homework or problem sets to get familiarize with

the topic.

If the lecturers can also provide some problems, it will be better.

Song Lingshuang Peking University

This is my first time to attend an international school abroad, so I am very excited

about meeting people from different countries and discussing with them. Also I am impressed by the beautiful scenery and delicious food in Japan. During this summer school, there are really many excellent lectures given by famous

professors from very good nuclear research groups all over the world. The lectures are precious resources for me to know more about different nuclear models, these new experiments, the research frontier, and so on. Sometimes I discuss with the lecturer, and they always kindly answer my questions. As a first year graduate student, I learned a lot from them. They arranged a tour to the RIBF. It’s very impressive and interesting. I visited these

huge facilities for the first time, and I got a lot of new knowledge from their explanation. So it is an unforgettable experience for me. I love the parties on the first day and the last day of this summer school. We have

delicious food and drinks, and chat with each other freely. We have a very good time! I am very happy that I make many friends from Japan, Vietnam, Ukraine, Canada,

and China. We spent a lot of time on discussion, which is helpful for all of us. We went sightseeing together, and now we know each other well. I keep in contact with some of them. Perhaps we can have some cooperation in the future. So, thank all the organizers of CNSSS for making this possible! In summary, I learned a lot and enjoyed myself in this CNS summer school. I wish

everything goes well.

Vi Ho Phong VNU Unversity of Science (Vietnam)

For me, the CNS Summer School will always be in my mind. It’s not only just because

that was my first travel to Japan and every things here was amazing, but also because of the knowledge about nuclear science that I’ve a chance to learn via lectures. This school brought the new vision about nuclear physics to me with many modern and hot topics related to nuclear physics. It showed me how the scientists in many countries and research fields involve in either a nuclear physics experiment or a theoretical study. I would like to say thank the organizer and all lecturers for brought us a successful

I am Nguyen Hoang Phuc, I am a PhD student at Institute of Nuclear Science and Technology, Hanoi , VietNam. This is the first time that I have had an opportunity to take part in CNS school, I

actually feel impressive, I met many leading physicists and followed their lectures. Almost of the lectures are difficult to me, but I like them, I will reread and try to understand them. I got much useful knowledge from this school, especially, from lecture of professor Descouvemont, his lecture mentioned on low energy reactions that I am caring about. I also had an opportunity to meet many international students, and take part in cultural exchanges. Everyone is kind and friendly. I discussed many problems with other students about nuclear structure, cluster model, experiment… This school is actually meaningful to me. I sincerely thank the organization for

supplying me the support and helping me to join this school. I also thank Hidetoshi Yamaguchi for his kindly help. I hope the CNS school will keep on in the future, if I have a chance, I am going to join this school next time.

In this summer school, I have learned a lot from the lectures, and learned what recent

progresses have been made in nuclear physics. Also, through communicating with other people, I learned what are the others groups doing. There are both theoretical and experimental topics in the summer school. And the

lectures were arranged not so tight, so that we don’t have to rush up in the morning. Between the lectures there were student sessions, where the young workers have chance to report their recent work. Because of the time is limited, maybe it’s a little hard for others in the different field to grasp the point. But still, we can find similar topics of our own research and discuss more detail afterwards. In the poster session, students were all very active. We walked around, look other

people’s work, asked them questions. And also, there were delicious food at the same time. We ate, we talk, we had a very good time.

During the summer school, we were arranged to take a visit at the RIBF. As a new theoretical student from China, this was the first time I saw the experimental equipment, and more important, one of the best equipment in the world. In the holiday, we take a look in Tokyo, and had a very good impression.

My experience at CNSSS12 was really wonderful and rewarding. I’m a graduate

student from China Institute of Atomic Energy. This is the first time that I have been to Japan. I benefit a lot from the summer school. The lectures given by excellent professors coming from different institutes around the

world were truly conducive to students. The lectures involved both the basic knowledge and frontiers of experimental and theoretical nuclear physics. I appreciated their

brilliant and lucid explanations. Tour to the RIBF was also very wonderful. The SRC is exactly very great. And

explanations from Prof. Tomohiro Uesaka were really clear and humorous. His enthusiasm inspired us. Last but not least, I would like to take this opportunity to thank the summer school

organizers for their diligent work, without whose contribution our experience at the summer school would not be the impressive as it is.

I am glad I can participate in CNSSS12. The lectures are very useful for me. Prof. Tien

Khoa Dao talked about some experimental research on nuclear scattering. I learned a lot from his lectures. Generally the lectures cover theoretical and experimental fields of nuclear physics. This summer school provides a good opportunity for me to meet foreign students and

doctors. The poster section is a good chance for us to communicate with each other. It is a good chance for me to visit RIBF facility. I have heard a lot about RIKEN facilities before. And this is my first time to see SHARAQ, EURICA and SAMURAI. Finally, thanks all the organizers for providing this good chance to study nuclear

physics.

First of all, I appreciate to the organizers of CNSSS12 and to the all of invited lecturers, too. This was my first participation of CNS Summer School. The lectures were quite helpful and it was my pleasure that I could meet some famous nuclear physicists there in person. And I think CNSSS is a good place for students to “exercise” presentation in front of the audiences. However, I wish that CNSSS be more exciting program, better than just like a “school”. I guess somebody feels like little bit boring when they listening the lectures for a whole day along. Of course the lectures were very nice and helpful. Actually, I expected something interesting activity between participants, especially students. Although this is an international program, we couldn’t make lots of friends during the program. Maybe the poster session was the only time to introduce each other and know about his/her own theme. I hope there are some real activities by participants such as group activity, quests or quiz sessions about nuclear physics etc.. I think the RIBF tour could make a good impression for the program and RIKEN. And

I like it so much even I usually working at the facilities. This RIBF tour might be done every year. I suggest why don’t we change the place for lectures because I feel that the Nishina Hall is not wide enough in that some participants, for instance, late comers couldn’t get their seat easily. Unfortunately, I can expect that there is no other available room for CNSSS in RIKEN. In my opinion, frankly speaking, this summer school has a basic part of “summer school” but I want to require something more exciting program. The lectures are not the only purpose of the CNSSS I think. We want to make some more friendships with foreign students.

Absolutely, this summer school gives me very deep impression for everything. You

have held a very successful summer school on CNS. Firstly, some very interesting reports about the nuclear physics were supplied by the

organizing committee, which include not only theoretical but also experimental

research area. As I am major in experimental nuclear physics, Prof. France's presentations about gamma-ray spectroscopy in exotic nuclei and other teachers' lecture for experimental nuclear physics attracted me very much. They let me learn the radioactive nuclei structure and the hot points of nuclear physics more deeply. And the introduction for experimental setup, e.g. GANIL and RIKEN setup, broadened my views and knowledge. Secondly, I am very happy to have the opportunity to visit the advanced RIKEN

accelerator facility. It is difficult for me to imagine how the so large-scale facility constructed at about 20 meters under the ground. It must be constructed very difficult and expend all scientists' and engineers' energies. The other surprising thing is that I met H. Haba-san, the leader of RI Application Team, as one of my colleagues works in his team at present. And I also visited their laboratory which also gave me very deep impression and is very

beneficial to my future research works. Lastly, all of the people, the organizers, the teachers and the students are very friendly and hospitable. The Japanese food is very fresh and nourishing. What I want to say is that it is my first time to eat the authentic Japanese special food, sushi. Very impressing! Finally, I want thanks again for the organizers to give me the opportunity to

participate this summer school. And I hope the school could continue year by year, and I really hope the Japanese and Chinese would have friendship forever.
