I have tried to use Binary Cascade (QGSP_BIC) and Bertini model (QGSP_BERT), or rather the PreCompound model they incorporate, to simulate the neutron yield produced by low-energy (3 MeV) protons interacting with a thin Li target. The experimental data suggests a rate of about 1000 neutrons per 4.5x10^6 incident protons, but I could not get any neutron produced in the simulation, with these two physics lists. The MCNPX code reproduced the data rather well, but we would like to compare the data also with the Geant4 results.
I would be very grateful if you could please recommend another model (or physics) I should be using to simulate these low energy processes.
Thank you very much,
