Broken Pairs and High-Spin States in Transitional Nuclei
The Interacting Boson plus broken-pairs Model has been used to describe high-spin bands in spherical and transitional nuclei. In the spherical nucleus $^{104}$Cd the model reproduces the structure of high-spin bands built on a vibrational structure. Model calculations performed with a single set of parameters reproduce ten bands in $^{136}$Nd, including the two dipole high-spin bands based on the $(πh_{11/2})^2$ $(νh_{11/2})^2$ configuration.
