Study of¹⁰⁸Mo nucleus in microscopic frameworks

Summary

The yrast spectra, reducedE2 transition matrix elements andQ _J+ values are calculated for¹⁰⁸Mo isotope by carrying out variation-after-projection (VAP) calculations. The experimentally available spectra upto 10⁺ are reasonably well reproduced. The yrast spectra upto 12⁺ and root-mean-square radii are also obtained in the framework of Cranked-Hartree-Fock-Bogoliubov (CHFB) Method. These calculations have been performed by employing a pairing-plus-quadrupole-quadrupole effective interaction operating in a reasonably large valence space outside the⁷⁶Sr core. Our results indicate that the axial VAP framework reproduced the observed spectra upto 10⁺ much better than the non-axial CHFB framework. The calculations seem to predict an axial symmetry for¹⁰⁸Mo to be confirmed experimentally.
