Projected Skyrme Hartree-Fock approach to structure of Mg isotopes

Skyrme-Hartree-Fock (SHF) calculations using the Cartesian mesh representation has been successful to describe ground-state properties of nuclei for a wide mass region. We extend the method so as to describe odd-parity excited configurations in the variation after parity projection (H.~Ohta, K.~Yabana, and T.~Nakatsukasa, Phys. Rev. C {\bf 70} (2004) 014301). The angular momentum projection in the full three-dimensional Euler angles has been performed for the first time in realistic calculations. Now the method is being applied to Mg isotopes. The ground-state correlation energies, excitation spectra, transition amplitudes, etc. are calculated. The calculation shows an importance of symmetry restoration.
