Abstract

The reactions ${}_{}{}^{48}{}_{}{}^{}\mathrm{Ti}(n, d){}_{}{}^{47}{}_{}{}^{}\mathrm{Sc}$, ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}(n, d){}_{}{}^{15}{}_{}{}^{}\mathrm{N}$, ${}_{}{}^{10}{}_{}{}^{}\mathrm{B}(n, d){}_{}{}^9{}_{}{}^{}\mathrm{Be}$, and ${}_{}{}^6{}_{}{}^{}\mathrm{Li}(n, d){}_{}{}^5{}_{}{}^{}\mathrm{He}$ have been studied at 14.4 MeV. The absolute differential cross sections have been analyzed using the distorted-wave method and assuming simple proton pickup. The effects of finite range, nonlocality, and radial cutoff have been investigated. Good fits obtained for the reactions ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}(n, d){}_{}{}^{15}{}_{}{}^{}N(\mathrm{g}.\mathrm{s}.\mathrm{})$, ${}_{}{}^{10}{}_{}{}^{}\mathrm{B}(n, d){}_{}{}^9{}_{}{}^{}\mathrm{Be}(\mathrm{g}.\mathrm{s}.\mathrm{})$, and ${}_{}{}^{10}{}_{}{}^{}\mathrm{B}(n, d){}_{}{}^9{}_{}{}^{}\mathrm{Be}\left(2.43\mathrm{} \mathrm{MeV}\right)$ yield spectroscopic factors in close agreement with shell-model predictions. The shape of the angular distribution of the reaction ${}_{}{}^{48}{}_{}{}^{}\mathrm{Ti}(n, d){}_{}{}^{47}{}_{}{}^{}\mathrm{Sc}$ is well explained, but a discrepancy in absolute magnitude of about a factor 4 is not yet understood. The agreement between theory and experiment for the reaction ${}_{}{}^6{}_{}{}^{}\mathrm{Li}(n, d){}_{}{}^5{}_{}{}^{}\mathrm{He}(\mathrm{g}.\mathrm{s}.\mathrm{})$ is not satisfactory, and this may indicate the importance of other processes such as knock-on.
