Abstract
We present Hartree-Fock-Bogoliubov (HFB) calculations of the ground st ates of even Mg isotopes. A Skyrme force is used in the mean-field cha nnel and a density-dependent zero-range force in the pairing channel. Our study shows that the ground states of Mg-36,Mg-38,Mg-40 are strong ly deformed with significantly different deformations for the neutrons and protons. Our study supports the disappearance of the N = 28 shell gap in the Mg isotopes.
