Abstract
The coupling between the rotational and shape degrees of freedom in so ft nuclei is studied using a constrained time-dependent Hartree-Fock a pproach. The dynamical equations an derived using the time-dependent v ariational principle on a restricted trial manifold consisting of cran ked squeezed states. This procedure is applied to describe the low-lyi ng isovector magnetic excitations observed recently in the gamma-soft nucleus Ba-134. The role of shape softness in the fragmentation mechan ism of the low-lying M1 strength is emphasized.
