Angular correlation measurements in the /sup 27/Al(/sup 16/O,. cap alpha. /sup 12/C) reaction at 65 MeV bombarding energy

Journal Article · · Phys. Rev. C; (United States)
An angular correlation measurement for the /sup 27/Al(/sup 16/O,..cap alpha.. /sup 12/C) reaction has been made at 65 MeV bombarding energy. The correlation was obtained by moving an ..cap alpha.. detector through an angular range of +10/sup 9/--+60/sup 0/ while the carbon detector was fixed at -30/sup 0/. The angular correlation is compared to two previous experimental studies of the same reaction at 65 MeV, to a Monte Carlo calculation of the incomplete fusion reaction, and to an inelastic breakup calculation. The measured angular correlation peaks near the most forward measured angle (theta/sub ..cap alpha../ = 11/sup 0/). This suggests that an incomplete fusion process, which predicts a peak in the angular correlation at 41/sup 0/, does not describe the ..cap alpha..+ /sup 12/C coincidence production. The inelastic breakup calculations do a good job of predicting the peak positions in the 65, 77, and 87 MeV angular correlation data. The success of the inelastic breakup calculations supports the supposition that the ..cap alpha..+ /sup 12/C production, in the 65--87 MeV energy range, is dominated by the sequential breakup process.
