I want to simulate the photon and neutron generation when the only one kind of high Z material(ex, Pb, Pt, W) bombarded with 20 MeV electron beam. So far, I found many papers that already calculated neutron flux using other Monte Calro code such as MCNPX, FLUKA but I failed with GATE. In my opinion, it doesn’t include the physics of photonuclear reaction to separate neutron from the nucleus directly by high energy photon. I Could you explain what is wrong in my physics setting as below here..? (I didn’t use hadronic process because that physics is regarding to the incident hadron.) Thank you in advance.
