The absolute differential cross section for the elastic scattering of 18-Mev protons has been measured for Al, Fe, Ni, and Cu at 35 or more angles between 15 degrees and 172 degrees. The estimated standard deviation of each point is 3 percent. The scattered protons are detected by a sodium iodide crystal whose energy resolution is about 2.5 percent, and the resulting pulse spectrum is recorded on a 15-channel pulse-height analyzer. For all materials used, protons scattered inelastically to the lowest known level are completely resolved from the elastic group. The differential cross sections for the four elements are qualitatively similar, showing pronounced structure and low cross sections in the background direction. Finally, the experimental results are in disagreement with cross sections predicted by the optical model of the nucleus.
