Abstract

Effective charges of electric quadrupole moments are calculated for sd and cross sd-pf shell isotopes with Z≥13. Perturbation theory of one-particle one hole with 2ℏω excitation is employed. Shell-model in the sd valence space is used for neutron number N ≤ 20. For neutron rich nuclei with N>20, sdpf valence space is used with full sd shell (Z-8) protons and full pf shell (N-20) neutrons. Good agreement is obtained with the measured data for most of the isotopes considered in this work while it deteriorates for some of them and need further investigation.
