Angular distributions for the elastic and inelastic scattering of 0.8 GeV protons from ${}_{}{}^{40}{}_{}{}^{}\mathrm{Ar}$ are presented. Cross sections for protons exciting states up to about 6 MeV were measured using a high-resolution spectrometer. Distorted-wave Born-approximation analyses of states of spin $2^{+}$, $3^{\mathrm{-}}$, $4^{+}$, and $5^{\mathrm{-}}$ were performed using collective-model transition densities.
