Description

Large-angle elastic scattering is considered within the framework of the method of the generalized matrix of reactions. The consideration is based on the analysis of amplitude singularities in the plane of the impact parameter. The power law of the cross section reduction is the sequence of analytical properties of the amplitude. An angular dependence of the cross section is calculated. It is determined with the function (1-cosTHETA)-3. This dependence agrees well enough with experimental data on scattering at large angles
