The ($p,n$) reaction has been studied at ${E}_{p}=23$ MeV on 35 nuclei ranging in mass from $^{9}\mathrm{Be}$ to $^{208}\mathrm{Pb}$. Overall energy resolution for the levels of interest ranged from 50 to 200 keV. Compound-nucleus contributions appear to be generally small at this bombarding energy. Early distorted-wave Born-approximation analysis of the data reveals several difficulties, both for macroscopic and microscopic forms of analysis.
