摘要：

The electric quadrupole moments Q of the B isotopes have been measured recently up to the mass number A = 17. The observed Q moment for B-17 as well as that for B-15 are very close to that for the N = 8 isotope B-13, contrary to the shell-model expectation with constant effective charges that Q increases rapidly with increasing number of neutrons added to the B-13 core. Analysis of these results reveals substantial reductions of the E2 effective charges for nuclei with large (N-Z)/A ratios, and cautions that the commonly accepted notion of constant effective charges may not hold in nuclei far from the beta-stability line. We discuss the variation of effective charges in relation to the change in properties of the isoscaler and isovector giant resonances in neutron rich nuclei.
