I am simulating neutron production through the 9Be(p,n) reaction (proton energy = 18 MeV). The problem that I have is with the physic list QGSP_BERT_HP.
I began my simulations with QGSP_BIC_HP and the results were close to the experimental ones. When I tried the QGSP_BERT_HP the results were more or less 8 times more neutrons produced.
I am using geant4 9.3 and I defined the physics packages making: runManager->SetUserInitialization(new QGSP_BERT_HP); or runManager->SetUserInitialization(new QGSP_BIC_HP);
These were the only changes between runs.
