I encountered a obstacle when simulated Al ion beam impinging on a carbon target


Good afternoon! When simulated 3 GeV Al ion beam impinging on a carbon target, I encountered a question that energy conservation violated. Meanwhile, another warning ‘INCL++/G4ExcitationHandler could not use its own level-density parameter for fission’ appears in the process of simulation. I use the geant4.10.07 patch-01 with physics list ‘QGSP_INCLXX’. Could you tell me how to tackle this situation?

Hello,

you may try out QGSP_BIC or QBBC. Energy/momentum non-conservation will be much more rare, however secondary particle distributions of INCLXX are more accurate in changed secondaries.
