The photographic emulsion technique was employed to study the scattering of 9.5-Mev protons by neon and argon. Energy levels of ${\mathrm{Ne}}^{20}$ at 1.58, 4.20, 4.95, and 5.62 Mev have been observed as well as of ${\mathrm{A}}^{40}$ at 1.48 Mev. Angular distributions have been determined for the protons elastically scattered by ${\mathrm{Ne}}^{20}$ and ${\mathrm{A}}^{40}$, as well as for the inelastic groups from the 1.58-Mev level of ${\mathrm{Ne}}^{20}$ and the 1.48-Mev level of ${\mathrm{A}}^{40}$.
