Abstract

The Interacting Boson plus broken-pairs Model has been used to describe high-spin bands in spherical and transitional nuclei. In the spherical nucleus 104Cd 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 136Nd, including the two dipole high-spin bands based on the (πh11/2)2 (νh11/2)2 configuration.
