Thank you for reporting problem. I just confirmed your problem and found what made this complete unphysical result. What I found is some sodium isotope data in G4NDL is incomplete, so that the problem also happens in reaction between neutron and some sodium isotope. Because the isotope is unstable, so that usual sodium element does not have the isotope fortunately. However, I also found at least several other isotope data are incomplete and make same troubles. Those data were introduced before I became developer. And new data which I introduced have not this trouble. However the replacement of wrong files is not light job at all. So I can not tell you when I will do it at this moment. Tatsumi |
When interacting 15 MeV neutron with Ne the secondary proton and neutron have the energy 675 and 681 MeV. Physics list _BIC_HP. Cross section for Ne element is replaced by sodium cross section.
