(d, α) Reactions on Some Light Nuclei

Abstract

Angular distributions of the emergent alpha particles from the reactions O 16 ( d , α 0 )N 14 (g'nd.), N 14 ( d , α 0 )C 12 (g'nd.), N 14 ( d , α 1 )C 12* (4.44 Mev state), F 19 ( d , α 0 )O 17 (g'nd.), F 19 ( d , α 1 )O 17* (0.872 Mev state) and P 31 ( d , α 0 )Si 29 (g'nd) were investigated at several bombarding energies in the region from 10.3 Mev to 11.4 Mev. The distributions which cover the angular range between approximately 25° and 160° in the center-of-mass system, exhibit generally oscillatory and forward peaking behavior. The intensity of the transition to the 2.31 Mev ( T =1) state of N 14 was measured in the range from 10.5 to 11.4 Mev in the step of 100 keV interval by aluminum absorber. The alpha particles from the targets were detected by a thin CsI(Tl) crystal scintillation spectrometer. The experimental results were compared with the theoretical curves calculated by simplified direct-interaction model of Butler and the model which includes heavy particle stripping process. The attempts t...
