Elastic and inelastic scattering of 17-MeV (center-of-mass energy) protons by ${\mathrm{Be}}^9$, ${\mathrm{B}}^{10}$, ${\mathrm{Ne}}^{20}$, ${\mathrm{Mg}}^{25}$, and ${\mathrm{Mg}}^{26}$ was studied using scintillation crystal spectroscopy. Angular distributions were obtained for most of the levels observed. All the angular distributions are characteristic of a direct interaction with initial-and final-state interactions. The differential cross sections were summed to obtain total cross sections which were compared to $\mathrm{EL}$ transition rates when known. For the larger ($p, p^{\prime }$) cross sections a strong correlation with the $\mathrm{EL}$ transition rates was found. This correlation is discussed in some detail.
