OBSERVATION OF C-12 CLUSTER TRANSFER BY ANGULAR-CORRELATION MEASUREMENTS

Angular correlations between deuterons and alphas in the reaction C-12 (N-14,d)Mg-24(alpha)Ne-2(g.s) at beam energies of 30, 33, 36, and 42 MeV have been used to investigate the reaction mechanism. Evidence for possible C-12 Cluster transfer to the 13.45 MeV 6+ state in Mg-24 is presented. The transfer of C-12(2+) clusters seems to be the dominant process. In addition to the correlation measurements, deuteron angular distributions were measured at 33 and 42 MeV and an excitation functi on at a lab angle of 8-degrees was obtained between 30 MeV and 45 MeV in 3 MeV steps. The angular correlations, deuteron angular distributio ns, and the excitation function were fitted using the finite range dis torted wave Born approximation (FRDWBA) and the Hauser-Feshbach formal ism of compound nucleus formation.
