I’m trying to simulate the as follow:
I have the electron beam with energy up to 50 MeV with detemined energy and angular distribution. This beam goes into a gold target (~ 1 mm thickness), also there is a probe, that consists from Au, Ta, In and Cr (total thickess 2 mm) materials and stands after the gold target. I’m measuring gamma spectrum right after the probe (gamma_spectrum.png), but there are missing lines around 200-400 keV according to an experiment. My question is: why don’t I have these lines? What should I do? PhysicsList is attached. Also I have already used standard physics lists, but had nothing.
Thank you in advance.
