B11(He3, α)B10Reaction at 33 MeV

Abstract

Differential cross sections of the ${\mathrm{B}}^{11}({\mathrm{He}}^{3}, \ensuremath{\alpha}){\mathrm{B}}^{10}$ reaction leading to seven states up to 5.2-MeV excitation energy have been measured at forward angles at an incident energy $E({\mathrm{He}}^{3})=33$ MeV. The angular distributions have been analyzed in terms of the distorted-wave Born approximation on the assumption that the direct neutron-pickup process is predominant. Relative spectroscopic factors have been extracted and are found to be in good agreement with Cohen and Kurath's theoretical predictions and with the results of the ${\mathrm{B}}^{11}(p, d){\mathrm{B}}^{10}$ experiment at 33.6 MeV.
