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.)
