### Abstract

The electric quadrupole moment Q for the ground state of [Formula Presented] was determined by the [Formula Presented]-NMR method applied to spin-polarized projectile fragments. From the measured quadrupole coupling constant, [Formula Presented] for [Formula Presented] in a Mg single crystal stopper the Q moment was deduced as [Formula Presented] As was the case in the previous [Formula Presented] result, the obtained Q moment is very close to that for the [Formula Presented] isotope [Formula Presented] in sharp contrast to the results of conventional shell-model calculations using constant effective charges. Comparison of the shell-model calculations indicates substantial reduction of the [Formula Presented] effective charges for isotopes with large [Formula Presented] ratios. The results were well accounted for in terms of [Formula Presented] dependent [Formula Presented] polarization charges as predicted by Bohr and Mottelson and by incorporating the decoupling feature of loosely bound particles.
