The code in the image below is from “NeutronHPphysics.cc” in the official example “Hadr04”.
My question is:
The applicable range of the thermal neutron elastic scattering model should be 0~4eV, so the maximum energy range should be set to 4eV. But why is the minimum energy set to 4eV in the red box in the picture? Did I misunderstand the SetMinEnergy() and SetMaxEnergy() methods?
