Abstract
The properties of light even and odd Xe and Ba nuclei (N and Z close t o 56) with respect to octupole deformation have been studied by the Ha rtree-Fock+BCS and the generator coordinate methods. None of the consi dered nuclei possess a stable static octupole deformation. However, we fmd that octupole collectivity is enhanced by dynamical correlations. Cranked shell model calculations indicate that octupole effects shoul d persist at least up to spins around 10HBAR.
