Angular distributions of four proton groups from the b10(d, p)b11 reaction

Abstract

Angular distributions have been measured of four proton groups from the B10(d, p)B11 reaction corresponding to transitions to the groundstate (group (0)) and the three lowest excited states of B11 (groups (1), (2) and (3)). A thin target of natural boron was bombarded with 310 keV deuterons and protons were detected by nuclear emulsions placed at 15 ° intervals round the target. Protons of different groups were distinguished by their range in the emulsion. Angular distributions of groups (0) and (2) are peaked in the forward direction while those of groups (1) and (3) are more nearly isotropic. By integration over solid angle total cross-sections were determined. They amount to 48 microbarn for group (0), 18 microbarn for group (1), 76 microbarn for group (2) and 11 microbarn for group (3).
