Coherent states model for three interacting bands of positive parity in the rotational limit and its extensive to negative parity bands

The coherent state model (CSM) which was previously proposed to describe the ground, beta, and gamma bands of even-even nuclei is considered for the special case of large deformations. Asymptotic expressions for the excitation energies and the B(E2) values are analytically written. The final formulas for energies are first tested on 232Th and then applied to several even-mass isotopes of U and Hf. Branching ratios are calculated for 232Th, where relevant data exist. The CSM is extended to that excited ocutpole bands are included. The numerical study shows very good agreement with the experimental data
