Abstract:

A list of cross section data and related information was compiled for total neutron cross sections and the reaction cross sections, n,p, n, alpha, and n,2n in the energy region around 14 Mev. This compilation includes published data through June 1963. A gamma ray spectral atlas containing 54 sets of spectra of some of the more common elements in the periodic table was obtained by activation analysis with 14.8 Mev neutrons. A one and a five minute irradiation of each element was made and spectra recorded at various times after irradiation to emphasize decay characteristics of the radioactive products from the irradiated element. Gamma ray peaks from the reaction products were identified as well as radioactive decay products from trace impurities in each element whenever possible. Carbon and nitrogen surface contamination of several high purity beryllium samples were measured by proton irradiation. The results seem to indicate that a large percentage of this contamination is in surface layers suggesting that these contaminants may have been added during a machining process. Author
