Abstract

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