摘要
The quadrupole moment of the proton drip-line nuclide O-13(I-pi = 3/2(-),T = 3/2,T-1/2 = 8.6 ms) has been determined for the first time by detecting its P-NQR signal following the production of polarized O-13 through the projectile fragmentation process in the O-16 + Be collision. The quadrupole moment has been determined to be /Q(O-13)/ = 11.0 +/- 1.3 mb. The present result together with the quadrupole moment of its mirror partner B-13 is compared with the theoretical values obtained by the shell model code, OXBASH, and by the Hartree-Fock calculation with its single proton separation energy taken into account.
