For elements heavier than Fe/Ni, alpha capture is endothermic, which implies that it could only happen if fast alphas are available. Furthermore, only a tiny fraction of fast alphas would actually undergo a reaction. IMO a more reasonable reaction involves the addition of a small cluster of H/D atoms. Such a reaction would be exothermic, and may well lead to the transmutation results found. Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
