Parity-Projected Skyrme Hartree-Fock And Angular Momentum Projection Approach To Mg Isotopes

We perform calculations of the variation after parity projection with Skyrme interaction for ground and excited states of even-even Mg isotopes. Using the 3D real-space representation, we can take into account any kind of deformation; e.g., cluster structure, gamma-deformation. We also perform the full 3D angular momentum projection to obtained rotational spectra and B(E2). In Mg-24, the ground K-pi = 0(+) and several odd-parity bands are calculated. In Mg-30,Mg-32,Mg-34, our calculation reproduces a breaking of the N = 20 magic number, so-called Island of inversion phenomena. Properties of both the ground and excited states are reasonably reproduced.
