Prolate-Oblate Difference and its Effect on Energy Levels and Quadrupole Moments

From the microscopic calculation for the W, Os, and Pt nuclei, we obtain semiquantitative relations among the prolate-oblate difference of the potential energy of deformation, the ${{2}_{\ensuremath{\gamma}}}^{+}$ and ${4}^{+}$ level splitting, and the static quadrupole moment ${{Q}_{2}}^{+}$. These relations are applied to $^{24}\mathrm{Mg}$, $^{56}\mathrm{Fe}$, $^{110}\mathrm{Cd}$, and $^{152}\mathrm{Sm}$. The important role of the $\ensuremath{\beta}\ensuremath{-}\ensuremath{\gamma}$ dependence of the mass parameters is demonstrated.
