摘要：

The electric quadrupole moment of B-17 and the g-factor of C-17 were measured by using the fragmentation-induced nuclear polarization technique combined with the beta-NMR method. The experimental quadrupole moment of B-17 is found strikingly close to that of the neutron closed-shell isotope B-13, indicating a strong quenching of the neutron E2 core-polarization charge. From the result obtained for the C-17 g-factor, we can conclude that the ground-state spin-parity of C-17 is 3/2(+).
