RESONANCE SPIN ASSIGNMENTS IN C-12-12(3(-)) INELASTIC-SCATTERING FROMANGULAR-CORRELATION METHODS(C)

Angular correlation techniques have been used to determine the spin of a strong resonance observed in the C-12 + C-12(3(-);9.64 MeV) inelast ic scattering channel, at a bombarding energy of 33.5 MeV in the cente r-of-mass system. The alpha particles produced in the sequential decay C-12(3(-))-->Be-8(g.s.) + alpha(0) were detected using four double-si ded silicon strip detectors. The data are consistent with a spin assig nment of J(pi)=18(+) for this resonance. The current results are compa red to calculations of resonance behavior in this system from the band crossing model.
