Measurements have been made of the asymmetric proton yields about the ${}_{}{}^5{}_{}{}^{}\mathrm{Li}$ recoil direction using the sequential reaction ${}_{}{}^6{}_{}{}^{}\mathrm{Li}({}_{}{}^3{}_{}{}^{}\mathrm{He},\alpha p){}_{}{}^4{}_{}{}^{}\mathrm{He}$ for both the ground and first excited states of ${}_{}{}^5{}_{}{}^{}\mathrm{Li}$ at a beam energy of 1.54 MeV. Measurements were made out of the reaction plane, and the results are in qualitative agreement with the predictions of a model proposed by Reimann, Martin, and Vogt. Distorted-wave Born-approximation stripping theory may also be capable of explaining the asymmetric results.
