Hi everyone, Really struggling to find anything on the internet to solve this problem. I really thought it would be an easy plug and chug equation..but I cant find it anywhere. Basically, I was asked to find what the maximum and average energy of secondary electrons produced by 2 MeV photon via compton scatter. I figured out the maximum, using correct equations..but I cannot find anywhere an equation that will help me calculate average electron energy. Any help will be appreciated...thanks.
