Angular distributions for theBe9(Li6,Li7)Be8reaction

Angular distributions for the ${}_{}{}^9{}_{}{}^{}\mathrm{Be}$(${}_{}{}^6{}_{}{}^{}\mathrm{Li}$, ${}_{}{}^7{}_{}{}^{}\mathrm{Li}$)${}_{}{}^8{}_{}{}^{}\mathrm{Be}$ neutron-transfer reaction to form the lowest two states in ${}_{}{}^7{}_{}{}^{}\mathrm{Li}$ have been measured for laboratory energies of 5.5 and 6.5 MeV. Elastic scattering cross sections for ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ on ${}_{}{}^9{}_{}{}^{}\mathrm{Be}$ were measured at laboratory energies of 4.0 and 6.0 MeV in order to determine optical potentials for the theoretical analysis of the transfer cross section. Distorted-wave-Born-approximation calculations were found to be in reasonable agreement with the data while Hauser-Feshbach calculations were not. This indicates that the reaction is primarily a direct process.
