Calculation of the variation after parity projection is performed in 3D Cartesian mesh representation for ground and excited states of even-even magnesium isotopes. The full 3D angular momentum projection after the variation provides rotational spectra for deformed nuclei. The method takes account of a part of octupole and rotational correlations beyond the mean field. We show the positive-parity ground band and the lowest negative-parity excited band in each isotope. Properties of the ground-state bands are in a good agreement with experiments.
