Abstract

We have employed the line shape analysis technique to study nuclear spin alignment produced in the C12 + O16 reaction populating the 2+ 4.43-MeV state in C12. We present excitation functions of m-substate population P(m) measured in the range Ec.m.=19-22.6 MeV and detailed angular distributions of P(m) obtained at Ec.m.=21.7, 21.9, and 22.3 MeV. Results have been analyzed in terms of a single resonance with sharp spin in the compound nucleus and found to contradict previous spin assignment based on studies of angular distributions of cross section in the Ec.m.22 to 22.6 MeV region. NUCLEAR REACTIONS C12(O16, C*12)O16, Elab=45-53 MeV. Measured σ(E;EC*12,θ), deduced C*12 (4.43 MeV, 2+) spin alignment (σ(E;m,θ)). O16 + C12 resonances, deduced J, π.
