| Research Abstract |
In order to understand the mechanism that anomalous nuclear structure appears in the neutron-rich region, the measurement of the nuclear magnetic moment for the isomeric excited state of^<32> Al, one of the neighboring nuclei of^<32> Mg for which anomalous nuclear structure was reported, was carried out. An innovative method to produce spin alignment in radioactive-isotope(RI) beams, the two-step fragmentation method with momentum-dispersion matching, was also developed in this study. In the experiment at RIKEN RIBF, we have succeeded to produce the RI beam of^<32> Al with 8(1)% of spin alignment by applying the new method as well as to determine the nuclear magnetic moment of the isomeric state of^<32> Al for the first time.
