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 contain ing 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. 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 portion 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
