Abstract
Quadrupole moments and effective charges are calculated for Li (A = 7, 8, 9, 11) and B (A = 8, 10, 11, 12, 13, 14, 15) isotopes based on the shell model with p and large basis spsdpf-shell model spaces. Excitations out of major shell space are taken into account through a microscopic theory which allows particle-hole excitations from the core and model space orbits to all higher orbits with 6ħω excitations. Effective charges are obtained for the neutron-rich Li and B isotopes which are smaller than the standard values for the stable p- and sd-shell nuclei. Our calculated Q moments agree very well with the experimentally observed trends of the recent experimental data.
