Angular correlation measurements, in the /sup 27/Al(/sup 16/O,..cap alpha.. /sup 12/C) reaction at 65, 77 and 87 MeV, were used to study the projectile fragmentation process. Three reaction models, incomplete fusion, inelastic breakup and elastic breakup were used to identify the reaction mechanisms responsible for the ..cap alpha.. + /sup 12/C production. Comparisons of the predicted angular correlations, from each of three models, were made with the measured angular correlations at 65, 77, and 87 MeV. The comparisons revealed, that inelastic breakup was the dominant reaction mechanism at all three energies. It was further determined that a small fraction (10-20%) of the ..cap alpha.. + /sup 12/C production resulted from the incomplete fusion process at 77 and 87 MeV. At 65 MeV it was found that incomplete fusion could be producing as much as 50% of the ..cap alpha.. + /sup 12/C pairs. The systematics of the measured angular correlations and the measured relative kinetic energy spectra, between the ..cap alpha.. + /sup 12/C ejectiles, further supports the conclusion that the inelastic breakup process is predominantly responsible for the ..cap alpha.. + /sup 12/C production in the 65 to 87 MeV energy range.
