ResumoThe question of validity of the pairing-plus-quadrupole model to well-deformed nuclei is examined. The calculated energy levels, $B(E2)$ 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 $K=0$ band and the $K=4$ band are examined in terms of model wave functions. For the sake of comparison and discussion, some results are also given for $^{154}\mathrm{Gd}$.[NUCLEAR STRUCTURE $^{156}\mathrm{Gd}$---calculated level energies, $B(E2)$ values, quadrupole moments, magnetic moments, $E2 \mathrm{and} M1$ matrix elements, $\ensuremath{\delta}(\frac{E2}{M1})$, ${\ensuremath{\beta}}_{\mathrm{rms}}$, ${\ensuremath{\gamma}}_{\mathrm{rms}}$. $^{154}\mathrm{Gd}$---calculated $B(E2)$ values. Comparison with experiment whenever possible.]
