摘要：
The shape evolution of even-even Mo isotopes from the line of stability up to the two-neutron drip-line is investigated within the self-consistent Hartree-Fock-Bogoliubov theory in both the axial and triaxial symmetries. The Skyrme energy density functional SLy4 has been considered in the particle-hole channel, while the zero range delta-interaction has been employed in the particle-particle channel. In order to correctly treat the pairing correlations, a particle-number projection was carried out by the Lipkin-Nogami (LN) method. The two-neutron separation energies and root-mean-square (rms) charge radii are investigated and compared with available experimental data. The evolution of the potential energy surfaces in the (beta, gamma) deformation plane is presented and discussed. In addition, the obtained ground state deformation parameters are compared to those obtained by other models.
