DIRECT DETERMINATION OF THE ALIGNMENT OF PROJECTILE FRAGMENTS FROM A BETA-ANISOTROPY LEVEL MIXING RESONANCE (LMR) MEASUREMENT

Using the Level Mixing Resonance (LMR) interaction, which converts ali gnment into polarization, the nuclear spin aligment of B-12 produced i n two different fragmentation reactions at intermediate energy (respec tively C-13 onto a C-12 target and Ne-22 onto a Be-9 target) was deter mined by measuring the beta-anisotropy. The nuclear spin alignment of N-18 fragments, produced in the Ne-22 reaction was measured for differ ent selections in the longitudinal fragment momentum distribution. In the same measurement the ratio of the quadrupole frequency to the magn etic moment nu Q/mu of neutron rich N-18 fragments implanted in mg was found to be an order of magnitude larger compared to simple shell mod el calculations.
