Cranked Nilsson-Strutinsky model applied to high spin states in Na22,23 : Systematics of rotational isomers and band terminations in the A=20-26 region

Headly, D. M. ; Sheline, R. K. and Ragnarsson, Ingemar LU (1994) In Physical Review C 49(1). p.222-232
Abstract

Previously proposed high spin states in Na22,23 are compared with calculations from the cranked Nilsson model including Strutinsky renormalization. High K rotational isomers are proposed for Iπ=6- in Na22 and 11/2+, 13/2+, and possibly 15/2+ in Na23. The positive parity yrast sequences in these two nuclei are analyzed in terms of the change from collective to single particle behavior at I=9 (22Na) and 17/2 (23Na). The systematics of band terminations in eight nuclei between Ne20 and Mg26 shows that Imax or Imax-1 has tentatively been reached in six of these eight nuclei, where Imax is the maximum possible sd shell spin for the given nucleus.
