  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 I=8, has a prolate well-deformed
shape. At higher spins the shape is triaxial with a "negative-gamma"
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.
