摘要

The low-lying rotational bands of triaxially deformed nuclei Pr-137, Pm-137 and Eu-139 are studied with a modified particle-rotor model following the nonadiabatic quasiparticle approach. The matrix elements of the odd-A nucleus are obtained in terms of a coupling matrix and the rotational energies of the even-even core. The spectra of the cores Ce-136, Nd-136 and Sm-138 indicate a strong influence of triaxial deformation and vibrational degrees of freedom. These properties are appropriately carried forward to the calculations for the odd-A nucleus. We demonstrate that the ground and side bands of the odd-A nucleus and its core can be explained with the same set of deformation parameters (beta(2),gamma). We argue that this method could be useful in studying the low-lying states in exotic nuclei also.
