Pairing-plus-quadrupole model calculations forGd154,156

The question of validity of the pairing-plus-quadrupole model to well-deformed nuclei is examined. The calculated energy levels, $B\left(E2\right)$ values, $\frac{E2}{M1}$ mixing ratios, and electromagnetic moments are compared with the experimental values of ${}_{}{}^{156}{}_{}{}^{}\mathrm{Gd}$ which is used as a test case. In particular, the structure of the second excited $K=0\mathrm{}$ band and the $K=4\mathrm{}$ band are examined in terms of model wave functions. For the sake of comparison and discussion, some results are also given for ${}_{}{}^{154}{}_{}{}^{}\mathrm{Gd}$.
