Abstract
The quadrupole moment Q of short-lived nuclei {sup 16}N(l{sup {pi}}=2;T{sub 1/2}=7.13 s) has been determined to be |Q({sup 16}N)|=(17.9{+-}1.7) mb by the {beta}-NMR/NQR technique. The magnetic moment of the nucleus was also determined to be |{mu}|=(1.9859{+-}0.0011) {mu}{sub N}. The obtained Q moment was significantly smaller than the shell model predictions even when a halo wave function was used. The present result strongly suggests serious quenching of the neutron effective charge. The most suited neutron effective charge e{sub n}{sup eff}=(0.20{+-}0.02) is even less than a half of the standard value, which may suggest smaller core polarization effect by the weakly bound valence neutron.
