Neutron total and inelastic scattering cross sections were obtained by time-of-fiight techniques for Na/sup 2//sup 3/. Results are given from 0.55 to 4.07 Mev. Measurements of the total cross section of a Pu/sup 2//sup 3//sup 9/ foil in the energy range from 0.00291 to 0.1 ev were made using a crystal spectrometer. Fission cross sections in the Mev region are given for U/sup 2// sup 3//sup 5/, Pu/sup 2//sup 3//sup 9/, and Pa/sup 2//sup 4//sup 1/. Measured values of effective cross sec tions for fission neutrons were obtained for (n,p) reactions on Ni/sup 5//sup 8/, Fe/sup 5//sup 4/, Zn/sup 6//sup 4/, Mg/sup 2//sup 4/, Fe/sup 5//sup 6/, Zn/sup 6/ /sup 7/, and Cu/sup 6//sup 5/. The standard notations for neutron cross sections used by the AEC Nuclear Cross Section Advisory Group are given. Resonance parameters in Th/sup 2//sup 3//sup 2/ are discussed. (M.C.(.)
