Thanks for you suggestion. One question: I may say that for energy conservation I've to take in account the binding energy of nucleons that were ejected from the nucleus (for water near 7.5 Mev per nucleon)? And so if at the end of the interaction I have extracted from the nucleus two nucleons I have to take in account 15 MeV?
