Abstract

The decay of sup149Er was investigated by -ray spectroscopy. Based on these measurements the ssub1/2, dsub3/2, and hsub11/2 neutron states in sup149Er and the ssub1/2, dsub3/2, dsub5/2, and gsub7/2 proton states in sup149Ho were identified. A systematic examination of these proton states in N=82 isotones indicates a modest closure at Z=64, rather than a major one as suggested previously. Spherical Hartree-Fock-Bogolyubov calculations for even-Z N=81 and odd-Z N=82 nuclei are compared with experiment.
