Half lives were determined for 10 transitions in low-lying energy levels, excited by slow neutron capture, in Mn/sup 5//sup 6/, Rh/sup 1//sup 0// sup 4/, Cu/sup 6//sup 4/, Al/sup 2//sup 8/, and I/sup 1//sup 2//sup 8/. Internal ma gnetic fields at the nuclei of Fe/sup 5//sup 7/ and Sn/sup 1//sup 1//sup 9/ in various magnetic media were studied with the Mossbauer effect, and their nuclear Zeeman effects were snalyzed. Energy spectra, angular distributions, and reduced widths were obtained for (d,t) reactions on Fe/sup 5//sup 4/, Fe/sup 5//sup 8/, Ni/sup 5//sup 8/, Ni/sup 6//sup 0/, and Ni/sup 6/>s1< s, and the data used to provide information on the ground-state wave functions of these isotopes. The beta and gamma radiations associated with Er/sup 1//sup 7//sup 2/ decay were measured and a decay scheme proposed for Er/sup 1//sup 7//sup 2/. The level structure of F/sup 2//sup 0/ at 1 to 150 kev above the neutron binding energy was studied by the F/sup 1//sup 9/(n,n)F/sup 1//sup 9/ ess. The region around 100 kev was found to contain a cluster of levels. A polystyrene film was prepared with a thickness of 530 A and its vacuum ultraviolet spectrum determined in the range 1100 to 2300 A. Experimental data on the kinetic energies of fragments from electron bombardment of ethylene and acetylene are interpreted in terms of a "temperature." The form factors for the inelastic scattering of high-energy electrons are calculated for Sm/sup 1//sup 5//sup 2/ with the collective model of a deformed nucleus. A singleparticle rotational model, which includes band mixing, was found to give a qualitative fit to many of the properties of the low- lying states in Fe/sup 5//sup 7/ with the exception of those depending on the intrinsic wave function of the 1/2/sup -/ ground state.
