摘要：

The frequency of occurrence of identical bands in superdeformed and normal-deformed nuclei is studied by carrying out a statistical analysis of a large number of rotational bands, which are generated with the reflection asymmetric shell model. The frequency of occurrence and the behaviors of identical bands revealed in the statistical analysis of the experimental bands were generally reproduced by the present theoretical simulation. This would indicate that the nuclear rnean-field approximation plus the beyond mean-field one, like angular-momentum and parity projections, can explain the phenomena of identical bands even though there is no available theory that can reach the accuracy of identity between the specific identical bands. Furthermore, the octupole effect on the identical bands is discussed. The present theoretical simulation shows that more correlations may lead to more identical bands.
