Reaction products from the bombardment of ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ and ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ gas targets with ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ beams have been measured at five laboratory energies between 70 and 160 MeV. Fusion, deep inelastic, and quasielastic processes were studied. Large deep inelastic yields (${\sigma }_{\mathrm{Di}}\gtrsim 600$ mb) with average $Q$ values of -50 MeV are present at the highest energy. Analysis of the fusion cross sections for ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$+${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ suggests that the maximum angular momentum in ${}_{}{}^{36}{}_{}{}^{}\mathrm{Ar}$ populated via this entrance channel may be as low as $29\pm 2\hslash$.

NUCLEAR REACTIONS ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$+${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$, ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$+${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$; $E_{\mathrm{lab}}=80\mathrm{} \mathrm{to} 160$ MeV. Measured elastic scattering, direct processes, deep inelastic processes, and fusion. All products with $Z>\mathrm{}4\mathrm{}$ identified. Measured angular distributions. Monte Carlo simulation of deep inelastic and fusion.
