Dear experts. With 12GeV proton beam bombarded Al target, and I just care neutron and proton after the interaction. so that what physicsList should I use in it? I tried to use FTFP_BERT_HP, QGSP_BERT... Compared with MCNP proton is good but neutron at low energy, the yield in Geant4 is only a half in MCNP. I think PhysicsList was not appropriate, can you suggest anything? Furthermore, whether using above PhysicsLists would be better or not? I felt that if use the various PL the runtime is also different and may be very slow, so to make the program fast and achieve a good result, which one I should use or make my own physicsList? Any Advice is greatly appreciated! Thank you very much.
