The structure of a neutron-rich $$^{25}$$F nucleus is investigated by a quasifree ($$p,2p$$) knockout reaction. The sum of spectroscopic factors of $$pi 0d_{5/2}$$ orbital is found to be 1.0 $$pm$$ 0.3. The result shows that the $$^{24}$$O core of $$^{25}$$F nucleus significantly differs from a free $$^{24}$$O nucleus, and the core consists of $$sim$$35% $$^{24}$$O$$_{rm g.s.}$$, and $$sim$$65% excited $$^{24}$$O. The result shows that the $$^{24}$$O core of $$^{25}$$F nucleus significantly differs from a free $$^{24}$$O nucleus. The result may infer that the addition of the $$0d_{5/2}$$ proton considerably changes the neutron structure in $$^{25}$$F from that in $$^{24}$$O, which could be a possible mechanism responsible for the oxygen dripline anomaly.

An electric quadrupole moment ($$Q$$ moment) is sensitive to collective aspects of nuclear structure. In the $$Q$$-moment measurement for unstable nuclei, we employ the $$beta$$-detected nuclear-quadrupole resonance method. In this method, we need to supply $$2I$$ resonance frequencies, where $$I$$ denotes the nuclear spin. We have developed a new RF-application system to induced all of the $$2I$$ transitions. The application of the $$2I$$ frequencies may be pursued in two different ways; the sequential RF pulse method and the mixed-wave RF pulse method. We confirmed the reversal of polarization for the both methods, from measurements of $$beta$$-ray asymmetry change for polarized $$^{12}$$B. Using this system, the $$Q$$ moments of $$^{31,32}$$Al have been measured to be $$|Q(^{31}{rm Al})| = 104(9)$$ $$e$$$$cdot$$mb and $$|Q(^{32}{rm Al})| = 24(2)$$ $$e$$$$cdot$$mb by the sequential RF pulse method.
