Differential cross sections for ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ + Ne

Accurate differential cross sections for elastic and inelastic ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ scattering by ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ and ${}_{}{}^{22}{}_{}{}^{}\mathrm{Ne}$ have been measured at up to 15 angles and in laboratory energy steps of ∼ 100 keV for $20<~E_{\mathrm{C}}^{\mathrm{lab}}<~34$ MeV ($12.5<\mathrm{}{E}_{\mathrm{c}.\mathrm{m}.\mathrm{}}<21.5\mathrm{}$ MeV). Several broad maxima appear in elastic scattering by ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ but not by ${}_{}{}^{22}{}_{}{}^{}\mathrm{Ne}$. The cross section for ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$(${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$, ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$) ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ was negligible in this energy range.

NUCLEAR REACTIONS ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ + ${}_{}{}^{20,22}{}_{}{}^{}\mathrm{Ne}$ elastic and inelastic scattering, $20<~E_{\mathrm{C}}<~34.4$ MeV; measured $\sigma (E, \theta )$ at 15 angles, $\Delta E_{\mathrm{C}}=100\mathrm{}$ keV; absence of yield to ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ exit channel.
