It has been shown that the cross sections at the energies 50-142.5 MeV, measured in the scattering angle range q < 90° and having Fresnel character, can be suc-cessfully described by means of a simple variant of the model with smooth angular-momentum dependence of the S-ma-trix. To describe the angular distributions at 32-41.17 MeV, measured in the whole angular range, the model has been modified to include al-lowance for indi-vidualized Regge poles, and the calculations have shown the important role of these poles in the formation of the anomalous large angle scattering pattern ob-served experimentally.
