Robin, "There could however be the occasional neutron from collisions of the S with other nuclei"
Occasional? I don't think so. My recollection it that the rule of thumb for spallation neutrons is 1 neutron per MeV of the accelerated particle (proton)... wouldn't more neutrons that be likely with the heavier accelerated ion, no? Even if not, I would think that there would be substantial spallation neutrons. That reaction seems most unlikely to me. But it raises the larger issue. Why the hell does everyone keep trying to shoehorn these reactions into KNOWN reactions? I'll give you big odds that eventually we will find that the culprit reaction is presently UUNKNOWN to us.
