Shape coexistence and high-spin states in 28Si

Ragnarsson, I. LU and Åberg, S. LU (1982) In Physics Letters B 114(6). p.387-391
Abstract

The spectrum of 28Si is investigated within the cranked Nilsson-Strutinsky model with all kinds of many-particle-many-hole excitations accounted for. Calculated excitation energies and quadropole moments are compared with experimental data. The recently observed backbend from 8+ to 10+ is suggested to be caused by the crossing of the oblate ground band with a prolate or slightly triaxial band having one proton and one neutron excited to the fp shell.
