Method of cross section difference is crucial to obtain X section on pure elements: • Using C, C2H4 è cross sections on C and H • Using C, C2H4, PMMA è cross sections on C, O and H

These are specific measurements related with PT & RPS. But we are open to suggestions!!!

PMMA is a combination

of C,O,H.
