Shell model studies in89Nb

Abstract

Experimental data on S9Nb are analyzed in terms of shell model calculations using 1 g9/2 and 2p~/2 valence nucleon orbits. The agreement between theory and experiment for the excitation energies and decay modes of the observed levels is very good. The possible properties of levels involved in weak or contaminated transitions at 2,523.7, 2,728.2 and 2,935.1 keV are indicated.

Status of the Nuclear Shell Model

“…Other recent studies in the fp shell include (84) and (164). Beyond the fp shell, "full-space" calculations are limited to the systems of identical nucleons (all protons or all neutrons) relative to a pair of doubly closed shells or to proton-neutron systems very close to such a (N = 48-50 and Z = 38-50) the smaller Og9/ 2 -1 PI/ 2 model space continues to be useful (166)(167)(168)(169)(170), although there are many known excited states that require additional configurations (165,(171)(172)(173).…”
