Angular distributions are presented for $\overline{p}-p$ elastic scattering at 8 and 16 GeV/c for $\mathrm{}\left|t\right|<1.3\mathrm{}$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^2$. At both energies there is structure in the differential cross sections in the region $0.5<~\mathrm{}\left|t\right|\mathrm{}<~1.0$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^2$, similar to that observed at lower energies. The diffraction peak continues to expand with increasing incident momentum.
