Phys. Rev. 185, 1416(1969.BThe statistical factor and the isospin-exchange factor are included in the normalization of Ref. 23, so that we have divided our result by 6 in order to make a direct comparison.The energy levels and transitions of~Au have been examined by high-resolution measurements of the y rays from the (n, n'y) reaction for incident neutrons between the energies of 0.2 and 2.2 MeV. The level scheme, up to an excitation of 1308 keV, is compared with a recent neutron time-of-flight study, and several new levels are proposed. Differential y-ray production cross sections at 95' are given and spin and parity assignments for levels in this nucleus are discussed.

High-resolution measurements of the deexcitation y rays from the~5As(n, n'y) reaction have been made at 0.1-MeV intervals for incident neutrons between the energies of 0.8 and 2.2 MeV.These y rays are assigned to energy levels up to an excitation of 1606 keV in~~A s. The level scheme is compared with that obtained in a recent resonance scattering experiment, and several new levels are proposed. Branching ratios and differential y-ray production cross sections at 95' are determined.
