Angular distributions for the elastic scattering of ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ from ${}_{}{}^{10}{}_{}{}^{}\mathrm{B}$ have been measured at $E_{\mathrm{c}.\mathrm{m}.\mathrm{}=14.17\mathrm{}}$, 16.15, and 18.65 MeV over an angular range from 20° to 176°. The angular distributions, which exhibit an oscillatory enhancement of the cross section at backward angles, are described by a scattering matrix parametrization, by adding a very narrow l window to the normal, strong absorption S matrix.
