Nd/sup 147/ was aligned and polarized at low temperatures in a neodymium ethylsulfate lattice. A saturation correction for susceptibility was verified. The effect of nondiagonal interactions on nuclear orientation was illustrated. Spin assignments of 5/2+, 3/2+, 5/2+, and 5/2+ were made for the excited states of Pm/sup 147/ at 91, 410, 531, and 686 kev, respectively. Mixing ratios were obtained for six mixed gamma rays in Pm/sup 147/. The magnitude of the amplitude mixing ratio delta (E2/Ml) Ml) was found to be approximately proportional to gamma -ray energy. Evidence was obtained that the beta branches with end points at 0.23, 0.38, and 0.81 Mev are mostly of the L = 0 type. (auth)
