B507 (2001) 115-120 | Subject: | nucl-th nucl-ex | Abstract: | Transition probabilities of the ground-state bands in $gamma$-soft nuclei are studied for the first time using the triaxial projected shell model approach. It is observed that the angular-momentum dependence of the transition quadrupole moment $Q_t$ is related to the triaxial deformation of the nuclear mean-field potential. The introduction of the $gamma$-degree of freedom in the shell model basis is shown to have a little influence on the {it constant} behavior of the low-spin $Q_t$ in a well-deformed nucleus. However, the {it increasing} collectivity with spin for the low-spin states in a $gamma$-soft nucleus can only be explained by considering the triaxial mean-field deformation. | Source: | arXiv, nucl-th/0103003 | Services: | Forum | Review | PDF | Favorites |
