Angular distributions of four neutron groups from the 10B(d, n)11C reaction

Abstract

Measurements are described of the angular distributions of the four most energetic neutron groups from the 10B(d, n)11C reaction at a deuteron energy of 0.6 MeV. Neutrons were detected by their recoil protons in nuclear emulsions. The angular distributions have been analyzed in terms of a stripping contribution and an, assumedly isotropic, contribution from compound nucleus formation. From Butler analysis lp = 1 is found for the stripping contribution of the neutron group leading to the 11C ground state, and lp = 0 for the group leading to the second excited state. This is in agreement with previous results obtained from the mirror reaction 10B(d, p)11B and with predictions from the nuclear shell model. Stripping contributions of the other two neutron groups are very small.
