Abstract

Spin-polarized radioactive ion beams are produced in the projectile fragmentation reaction induced by intermediate-energy heavy ion beams. The degree of spin polarization shows characteristic dependence on the outgoing momentum of the projectile fragment in the magnitude around 1 ∼ 10 %. The qualitative behavior is well described by the kinematical model of the fragmentation process. Recently, we have successfully produced spin-polarized beams of aluminum isotopes in the mass A ∼ 30 region via the fragmentation of 95 MeV/u 40Ar projectiles. The magnetic moments of 30Al and 32Al and the electric quadrupole moments of 31Al and 32Al have been measured using the β-NMR technique with the polarized RI beams of the Al isotopes.
