OK, now I look more carefully at the source code at ~/geant4.6.2.p01/source/particles/management/src/G4NeutronBetaDecayChannel.cc
and realize that final-state proton is hard-coded as being at rest in G4NeutronBetaDecayChannel.cc ;8-(
// daughter 2 (proton) at REST G4ThreeVector direction2(0.0, 0.0, 0.0); G4DynamicParticle * daughterparticle2 = new G4DynamicParticle( daughters, direction2); products->PushProducts(daughterparticle2);
That, of course, decreases the usefulness of the G4 code, and will force me to write a new version of NeutronBetaDecayChannel code where the proton kinetic energy properly varies from 0->780 eV in the phase space manner.
