Recent experiments by Cohen on the inelastic scattering of protons by nuclei of medium Z have shown some unexpected effects, in particular, a pronounced increase in cross section at excitations of 2-3 mev in all elements with Z between 40 and 52. A search for this `anomalous scattering' has been made in Sn, In, Cd, Ag, Pd, Mo, Nb, Zn, Cu and Ni, using 9.8 mev protons. The prominent effect at excitations of 2-3 mev was not found at 9.8 mev. In Cu, Zn and Ni an intense group corresponding to excitations of 1-1.4 mev was observed, in agreement with Cohen's results. |
