Re: Question Li7 neutrons production (David)

I am working on a similar problem only at 2 MeV proton energy. A new physiclist, QGSP_BIC_AllHP, has been added for geant4.10.02 which supposedly has better physics for low energy proton; however, I think I have found a bug in it that I am still checking. It gives too much energy to the seconadary neutrons. I believe the mistake is that the proton charge is not subtracted at line 268 of G4ParticleInelasticCompFS.cc.

I think it should read:
    // Watts fix 12/17/2015 G4double residualZ = theBaseZ - aDefinition->GetPDGCharge();
    G4double residualZ = theBaseZ - aDefinition->GetPDGCharge()+theProjectile->GetPDGCharge();

(I have not vested this with any of the experts yet.)
