Five-nucleon simultaneous and sequential transfer in theC12(11B,6Li)17O andC12(d,7Li)7Be reactions

Abstract

Measurements of the angular distributions of the {sup 12}C({sup 11}B,{sup 6}Li){sup 17}O reaction were performed at three energies of a {sup 11}B beam: 28, 35, and 40 MeV. The results were analyzed in the frame of the exact finite range distorted wave Born approximation of the first and the second order assuming the simultaneous and sequential transfer of the neutron and the {alpha} particle. Such an analysis was also performed for previously measured angular distributions of the {sup 12}C({ital d},{sup 7}Li){sup 7}Be reaction at {ital E}{sub lab} = 78 MeV. In both reactions under investigation dominance was found of the simultaneous transfer of the {alpha} particle and the nucleon correlated to the {sup 5}He ({sup 5}Li) cluster in the ground or the first excited state. {copyright} {ital 1996 The American Physical Society.}
