Abstract
Low-lying energy spectra of some odd-A isotopes of Lu and Ta are predicted using the quadrupole-quadrupole interactions as the effective residual interaction together with the usual spin-orbit and extrapolation terms in the Hamiltonian. It is suggested that the Coriolis antipairing (CAP) force might generate the correct doublet structure of the 1/2+ bands, especially in highly deformed regions. It is shown that the pseudo-SU(3) model satisfies the general requirement that it is capable of describing the spectral behaviour of different nuclei with only minor variations in the strength parameters. Correlations between the band excitation energies and the strength parameters are also given in a first approximation. The ratios of interband M1 transition probabilities are also presented.
