In a study of the system ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$+ ${}_{}{}^{48}{}_{}{}^{}\mathrm{Ca}$ at $E_{\mathrm{lab}}\left({}_{}{}^{16}{}_{}{}^{}\mathrm{O}\right)=158.2\mathrm{}$ MeV, we have measured elastic, inelastic, and single-nucleon transfer cross sections to resolved final states, and the non-fusion reaction cross section. The measured cross sections to resolved states generally agree with the predicted magnitudes and angular distributions from exact finite-range distorted-wave Born approximation calculations. The total non-fusion reaction cross section, ${\sigma }_{\mathrm{NF}}$, is measured to be ${0.66}_{-0.07\mathrm{}}^{+0.27\mathrm{}}$ b. These results are compared with other studies made at different bombarding energies, and for other systems.
