Large-Scale Shell Model for Nuclear Structure and Nuclear Astrophysics Studies

Abstract

The study of neutron-rich nuclei near 132Sn is interesting and important for both nuclear structure and nuclear astrophysics. For a considerably large model space allowing cross-shell excitations, a new effective Hamiltonian is determined by employing the extended pairing-plus-quadrupole model with monopole corrections. Calculations for two mass regions, for the north-east quadrant of 132Sn with Z > 50 and N > 82 and for the south-west quadrant with Z be clearly seen.
