Angular distributions for the elastic and inelastic scattering of 0.8 GeV protons from ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ and ${}_{}{}^{22}{}_{}{}^{}\mathrm{Ne}$ are presented. Cross sections for protons exciting states up to about 14 MeV were measured using a high resolution spectrometer. Coupled-channels analyses of scattering cross sections for the $0^{+}$, $2^{+}$, $4^{+}$, and $6^{+}$ states in the ground-state rotational band, possible $2^{\mathrm{-}}$, $3^{\mathrm{-}}$, and $5^{\mathrm{-}}$ members of a $K^{\pi }$${=2\mathrm{}}^{\mathrm{-}}$ octupole band, and possible $1^{\mathrm{-}}$, $3^{\mathrm{-}}$, and $5^{\mathrm{-}}$ members of a $K^{\pi }$${=0\mathrm{}}^{\mathrm{-}}$ octupole band in ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ were performed. Also reported are coupled-channels analyses of the experimental angular distributions in ${}_{}{}^{22}{}_{}{}^{}\mathrm{Ne}$ for the $0^{+}$, $2^{+}$, and $4^{+}$ states in the ground-state band, the $K^{\pi }$${=2\mathrm{}}^{+}$ γ-vibrational band members, and the $2^{\mathrm{-}}$ and $3^{\mathrm{-}}$ members of a $K^{\pi }$${=2\mathrm{}}^{\mathrm{-}}$ octupole band. Deformation parameters for states not in the ground-state rotational bands are obtained from a distorted-wave Born approximation analysis of these data. Multipole moments inferred from the deformed optical potentials are compared with moments obtained with electromagnetic measurements, low-energy proton, deuteron, ${}_{}{}^3{}_{}{}^{}\mathrm{He}$, and ${}_{}{}^4{}_{}{}^{}\mathrm{He}$ scattering, and shell-model calculations.
