The polarization of protons from the ${}_{}{}^7{}_{}{}^{}\mathrm{Li}({}_{}{}^3{}_{}{}^{}\mathrm{He},\overrightarrow{\mathrm{p}}){}_{}{}^9{}_{}{}^{}\mathrm{Be}$ reaction was measured at four laboratory angles between 70° and 85° at a bombarding energy of 14 MeV. The results are in marked disagreement with earlier reported measurements performed under similar conditions. A comparison between our polarization measurements and previous analyzing power measurements for the inverse reaction initiated by polarized protons shows no evidence for violation of time-reversal invariance as claimed.
