Popis:	The elastic and inelastic (leading to the first excited states of target nuclei) scatterings of protons by medium weight nuclei (Ti, Cr, Ni, and Zn) were studied by observing the dependence of their angular distributions on bombarding energies from 8 MeV to 14 MeV. The angular distributions of protons elastically scattered from oxygen were also measured in the same energy range. There are appreciable regularities in the elastic scatterings by medium weight nuclei as regards the dependence of their angular distributions on the bombarding energy and on the atomic number except in the case of the bombarding energy of 8 MeV. The elastic scatterings from oxygen show an anomalous behaviour at energies about 9 MeV. The angular distributions of protons inelastically scattered from medium weight nuclei can be fitted by the predictions of the direct interaction theory with Born approximation at about 14 MeV, but at the lower bombarding energies they seem not to do so, although they have the prominent forward peaks....
