We have measured the inelastic scattering cross section for the reaction ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$(${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$, ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$')${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$. The inelastic yield is dominated by single and double excitation of the group of states with $6.1<~E_x<~7.1$ MeV in ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$. The yield for energy losses greater than 15 MeV is 5.9 mb. This is significantly less than time-dependent Hartree-Fock calculations indicate for this system where nonfusion for low partial waves is predicted.
