Deformation of nuclei close to the two-neutron drip line in Mg region

  • Published:
Acta Physica Hungarica New Series Heavy Ion Physics

Abstract

We present Hartree-Fock-Bogoliubov (HFB) calculations of the ground states of even Mg isotopes. A Skyrme force is used in the mean-field channel and a density-dependent zero-range force in the pairing channel. Our study shows that the ground states of36,38,40Mg are strongly deformed with significantly different deformations for the neutrons and protons. Our study supports the disappearance of theN=28 shell gap in the Mg isotopes.
