In reply to H Veeder's message of Sat, 14 Sep 2013 00:19:44 -0400: Hi, BTW here are a few potential neutron producing reactions:-
14N+15N => 28Si + n + 16.386 MeV 16O+18O => 33S + n + 12.996 MeV 14N+18O => 31P + n + 18.451 MeV 16O+17O => 32S + n + 12.399 MeV 15N comprises 0.365% of natural N. 17O comprises 0.037% of natural O. 18O comprises 0.2% of natural O.
