Varying shell gap and deformation inN∼20unstable nuclei studied by the Monte Carlo shell model

The structure of neutron-rich nuclei in the $N\ensuremath{\sim}20$ region is studied by the Monte Carlo shell model based on the quantum Monte Carlo diagonalization method. We present a comprehensive description of even-even isotopes of O, Ne, Mg, and Si. It is demonstrated that, for different nucle... View More
