Total Neutron Yields from Light Elements under Proton and Alpha Bombardment

Total neutron production cross sections have been measured for targets of D, T, Li/sup 7/, Be/sup 9/, B/sup 11/, C/sup 13/, C/sup 14/, and F/sup 19/ under proton bombardment and of Li/sup 7/, Be/sup 9/, B/sup 10/, and Si/sup 29/ under alpha-particle bombardment. Energy ranges covered differ, but were contained between threshold and 5 Mev for protons and between threshold and 9 Mev for alphas. In several cases cross sections for the inverse reactions, (n,p) and (n, alpha ), have been computed and compared, where available, with direct measurements. (auth)
