Particle-drip lines from the Hartree-Fock-Bogoliubov theory with Skyrme interaction

Abstract

We calculate positions of one- and two-particle, proton and neutron drip lines within the Hartree-Fock-Bogoliubov theory using Skyrme interaction. We also determine an approximate r-process path defined as a line where the neutron binding energy is equal to 2 MeV. A weakening of the nuclear shell structure at drip lines is found and interpreted as resulting from a coupling with continuum states.
