Abstract
Microscopic effective charges and quadrupole moments of sd-shell and sd-pf cross-shell nuclei with Z≥13
Highlights
The nuclear quadrupole moment, is considered as a probe for the deviation of nuclear charge from spherical symmetry
Results based on the sd-shell interactions USDB for sd-shell model space [14] and the sdpf interaction sdpf-u [15] for sdpf model space with valence protons are restricted to the sd shell and N-20 neutrons to the pf shell
The Hamiltonian USDB leads to a new level of precision for realistic shell model wave functions
Summary
The nuclear quadrupole moment, is considered as a probe for the deviation of nuclear charge from spherical symmetry. Effective charges and quadrupole moments of sd- and sdpf-shell isotopes (Z≥13): sd and sdpf- shell model, core-polarization effects. Values with shell-model wave functions using a least-squares fit with two free parameters gave standard proton and neutron effective charges, eeff p
