Triaxiality in 48Cr

Abstract

Rotational behavior inducing triaxiality is discussed for 48Cr in the cranked Nilsson-Strutinsky (CNS) model, as well as in the spherical shell model. It is shown that the low-spin region up to about 1 = 8, has a prolate well-deformed shape. At higher spins the shape is triaxial with a 'negative-γ' deformation, that is, with rotation around the classically forbidden intermediate axis. By comparing calculated B(E2)-values and spectroscopic quadrupole moments in the CNS with spherical shell model results and experimental data, the triaxial rotation around the intermediate axis is confirmed.
