Reflection Asymmetric Shell Model for Octupole Nuclei
-
-
Abstract
The reflection asymmetric shell model approach has been developed for the description of octupole deformed nuclei. The Q· Q forces of quadrupole, octupole and hexadecapole as well as the monopole and quadrupole pairings are included in the Hamiltonian. The shell model space is spanned by a
selected set of the projected axial and octupole Nilsson + BSC basis. The general features of experimental octupole rotational bands can be reproduced and interpreted by the present model. The experimental superdeformed band states in 190, 194Hg are well reproduced by the present calculations, which provide theoretical support to the possible experimental evidence for the discovery of the octupole superdeformed rotational bands.
