Abstract
The absolute differential cross section for the elastic scattering of 17.00±0.05 Mev (center of mass energy) protons has been measured for twelve elements: Be, C, Al, Fe, Co, Ni, Cu, Zn, Rh, Ag, Pt, and Au. Between 31 and 39 angles were taken for each element with a five-degree (or less) interval ranging from 15 to 172 degrees. The estimated standard deviation of each point is 2.5%. The scattered protons are detected by a NaI(Tl) crystal whose energy resolution is about 2.5%, with the result that in the majority of cases all inelastically scattered protons are rejected.
