The availability of charged-particle accelerators made the intensive study of the interaction between protons and atomic nuclei possible; the angular distribution of the protons was found to be especially sensitive toward the effect of the individual properties of the nuclei on the elastic scattering of protons. Similar work was previously carried out with the 5.4-Mev and the 19.6- Mev linear accelerators of Physico-Techn. Inst. in Rnarkov and on the cyclotron of the Physical Inst. of the Ukrainian Academy of Sciences. Results indicated that the angular dependence of the ratio of the measured and Coulomb cross sections presents a different character for nuclei with even or odd mass numbers, if the number of neutrons of the even nucleus is close to a magic number. A different situation arises if the number of nucleons in the nucleus are arranged by unit, regardless whether the nucleon is charged or not. The elastic scattering of 19.6-Mev protons was studied in the case of the following isotopes: T, He/sup 3/, He/sup 4/ Li/sup 6/, Li/sup 7/, N/sup 14/ O/sup 1 6/ Co, Cu/sup 63/ Ge/sup 73/, Ge/sup 74/, Cd/sup 11/1, Cd/sup 113/, Cd/sup 116/, Sn/sup 116/ ,Sn/s up 117/, Sn/sup 118/ Sn/sup 119/ Sn/sup 120/ Sn/sup 122/ Pb/sup 2O7/ Pb/sup 208/ and Bi. The data obtained with Co, Cu Cd, and Sn isotopes indicate a diffraction-type scattering; the optical model illustrates well the elastic scattering of protons on atomic nuclei. (TTT)
