Hello,
I noticed that no conversion electrons are produced from neutron inelastic scattering in G4HadronPhysicsQGSP_BIC_HP. There is a flag: G4ParticleHPManager::GetInstance()→SetUseOnlyPhotoEvaporation(true), but this only affects the G4NeutronHPCaptureFS.cc file, and therefore only handles the deexcitation properly in the neutron capture case. Is there a specific reason that the neutronInelastic scattering process spawns gamma rays directly at the interaction vertex instead of accounting for the lifetimes of the excited nuclear states, and internal conversion electron probabilities? For many elements such as Xe-129 the conversion electron probability of the 1st excited state is ~90%, so this is not generally a small effect. Many state lifetimes are long compared to the trajectory lifetime of the particle (F-19 2nd excited state has 89 ns T1/2), which means that these gamma rays should be emitted from the end of the track instead of the interaction vertex.
Are there any plans to implement a more accurate treatment of this process, similar to the neutron capture flag?
Kind regards,
Tim
