Activation Cross Sections for 14-Mev Neutrons

Cross sections for several nuclear reactions induced by 14-Mev neutrons were measured by the activation method. The number of activated atoms was determined by absolute beta-counting. Corrections for finite sample thicknesses were determined experimentally in every case. Cross sections for the following reactions were measured: ($n,2n$) for Cu⁶³, Cu⁶⁵, Ag¹⁰⁷, and Ag¹⁰⁹; ($n,p$) for Al²⁷, P³¹, Fe⁵⁶, and Cu⁶⁵; (n,α) for Al²⁷.
