Abstract

To produce a radioactive-isotope (RI) beam with high spin alignment, we have developed a novel method, the two-step projectile-fragmentation (PF) method, that employs momentum-dispersion matching. An on-line experiment to produce 32A1 from 48Ca via 33A1 was performed at RIKEN RI Beam Factory. In the experiment, we succeeded in producing approximately 8% spin alignment in an RI beam of 32A1. In this paper, we focus on evaluating the magnitude of spin alignment realized in one-nucleon removal from 33A1.
