Ru114in axial and nonaxial microscopic frameworks

The yrast spectra, reduced E2 transition matrix elements, and ${\mathit{Q}}_{{\mathit{J}}^{+}}$ values are calculated for the ${}_{}{}^{114}{}_{}{}^{}\mathrm{Ru}$ isotope by carrying out variation-after-projection calculations. The experimentally available spectra up to ${10}^{+}$ is reasonably well reproduced. The yrast spectra up to ${20}^{+}$ and root mean square radii are also obtained in the framework of the cranked-Hartree-Fock-Bogoliubov method. These calculations have been performed by employing a pairing–plus–quadrupole-quadrupole effective interaction operating in a reasonably large valence space outside the ${}_{}{}^{76}{}_{}{}^{}\mathrm{Sr}$ core. Our results indicate that there is a tendency for the nonaxiality to increase as we move along the yrast states. © 1996 The American Physical Society.
