• The elastic scattering of 13-42 Mev alpha-particles by heavy elements has been analysed, using the boundary condition model of Feshbach and Weisskopf and the optical model with a complex potential of exponential shape in addition to the Coulomb potential. Results for Ag and Au have been compared with experiments for the energy dependence of the elastic scattering and its angular distribution at 22-Mev. As for the energy dependence the experimental data have been fitted fairly well with the results derived from both models, but for the angular distribution the agreement between experiments and theories is less satisfactory, especially for Ag data. The best-fit procedure compels us to assume a considerably larger value for the radius of the alpha particle than the usually accepted value, R_α〜1.2×10^<-13>cm, using R=γ_0A^<1 / 3> with γ_0=1.5×10^<-13>cm for the nuclear radius.
