I’m trying to simulate a source of Cf-252 moderated by polyethylene and a Li-6 based thermal neutron detector and have some questions about how to ensure thermal neutron scattering is handled correctly:
Currently I have
G4HadronPhysicsQGSP_BIC_HP(among other standard physics) in my modular physics list. I also need to add the thermal scattering libraries (
G4NeutronHPThermalScatteringData) as shown in Section 5.2 of the Book for Application Developers, correct?
I’m using the NIST
G4_POLYETHYLENEmaterial for my moderator. Do I understand correctly that
G4ParticleHPThermalScatteringNames.ccautomatically overrides the hydrogen content of the NIST material with the correct thermal scattering version? Or do I need to build it myself from elements using
