I am shooting neutrons to gadolinium mix with water. I want to count how many neutron captured on hydrogen and gadolinium. I have found a question as Find nucleus involved in nCapture process in Geant4 Answer given here this link https://stackoverflow.com/a/18934601/18348296 . Could anyone say how these two classes myParticle and myMC will look like? Or is this necessary to construct these two data classes ?
How can I count the number of neutron captured on gadolinium and hydrogen?
