Vector and tensor analyzing powers (${\mathit{iT}}_{11}$, ${\mathit{T}}_{20}$, ${\mathit{T}}_{21}$, and ${\mathit{T}}_{22}$) for ${}_{}{}^6{}_{}{}^{}\to$${+}^{12}$C elastic scattering are presented for a ${}_{}{}^6{}_{}{}^{}\to$ bombarding energy of 30 MeV over the c.m. angular range 15°–138°. The results of optical model calculations made with central, spin-orbit, tensor and angular momentum dependent potential terms show that the large angle data for the vector and tensor analyzing powers are sensitive to the presence of a static spin-orbit term. The nonzero ${\mathit{T}}_{21}$ data show that a tensor potential must be included to describe ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ scattering.
