I am having some problems with the scoring of energy deposition of secondaries. I shoot a 100 MeV proton beam to a tungsten thin layer, neutrons are generated by (p, xn) reactions then go through a polyethylene moderator and some of them get into a He3 detector and occur some reactions with He3. How can I get the deposited energy of each the secondary neutron in the detector?
I assume that most of the neutrons are thermal energy and the particular reaction of the thermal neutron (<0.0025 eV) is n + He3 -> (191keV) Triton + (573keV) proton + Q=764 keV. As I calculated, if the primaries are thermal neutrons and the Triton and the proton will be absorbed in the detector, the deposited energy of each the event will be 764 keV, Why? Sorry for the lacking of my knowledge about that problem.
