Stable collective triaxial rotation in Kr-77

Steinhardt, T.; Eberth, J. and Ragnarsson, Ingemar LU (2007) In European Physical Journal A. Hadrons and Nuclei 33. p.303-306
Abstract
Based on the gamma-spectroscopic analysis of G.N. Sylvan et al., configuration-dependent cranked Nilsson-Strutinsky calculations have been performed. They describe the nucleus Kr-77 globally in good agreement with the experimental findings and the expectations derived from single-particle orbitals in a deformed potential. Within these calculations, the unambiguous assignment of a configuration with three protons and five neutrons in the g(9/2) shell to the high-spin Yrast states of negative parity indicates that the nucleus Kr-77 has stable triaxial deformation and rotates about the intermediate axis. This not only disproves the recent interpretation of an occupation of the d(5/2) orbital being responsible for the strong deformation in... (More)
