Neutron-rich nuclei around N=16 shell closure

摘要

The disappearance or weakening of traditional shell closures and appearance of new magic numbers for very neutron-rich nuclei is mainly due to tensor force. In this work the low lying spectra, transition rates B(E2) and quadrupole moment of neutron rich 220,240,26F an d 28 F isotopes were studied by performing shell model calculations for somewhat different types of interactions.
