A study was made of the angular distribution of protons with initial energy 5.4 Mev, elastically scattered by nuclei of beryllium, carbon, fluorine, magnesium, aluminum, calcium, manganese, nickel, copper, and zinc. The protons scattered by angles from 20 to 160 d were simultaneously recorded by photographic plates. The angular resolution was plus or minus 2.5 d . The targets employed were thin (several microns) films or foils. The angular distribution obtained for the scattered protons differs sharply fromn the Coulomb distribution, and is not the same for the vsrious nuclei. For beryllium and carbon a large maximum of scattering was observed near 150 to 160 d , but the ratio of the cross section of the nuclear scattering to the Coulomb scattering in carbon is four times greater than in beryllium. This was attributed to the formation of a intermediate N/sup 13/ nucleus, which has an excitation level in this region, and consequently resonant scattering takes place. The scattering of manganese and aluminum is similar. The distributions for nickel, copper, and zinc sre identical. For manganese the qualitative course of the distribution is analogous to that of the proceeding elements, but the minimum and the second maximum are shifted towards the larger angles. An unexpectedly large value was obtained for the ratio for calcium, particularly at large angles. For heavier nuclei thene was a pronounced manifestation of the interference nature of elastic scattering. Attempts to treat the results in accordance with an optical model were not successful.
