Large-Scale Shell Model for Nuclear Structure and Nuclear Astrophysics Studies
-
摘要: 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 < 50 and N < 82, have been performed recently. The structure of these nuclei is analyzed in detail, and the role of the monopole corrections can
be clearly seen.Abstract: The study of neutron-rich nuclei near 132Sn is interesting and important for both nuclear structure and nuclear astrophysics.
