Triaxial models description of the low-lying properties in Os-192

摘要

Several typical triaxial models have been parallel addressed and applied to describe the energy values and B(E2) transitional rates in the ground band and the gamma band for Os-192. It is shown that the different triaxial model presents different triaxial dynamics but each of them can only succeed to explain part of the spectral properties of this nucleus, which indicates that the triaxial shape of Os-192 may be more complicated than that reflected by an ideal triaxial model. In addition, the staggering signature in experiments hints that gamma-rigid triaxiality should be more or less involved in Os-192.
