The peratization approximation

[摘要] The peratization program is investigated in the field of singular potential scattering, as an analog to the unrenormalizable field theories. We review some known results on the scattering amplitude, and establish the applicability of the commonly used regularizations. A general argument for peratization is presented. Several examples are considered. The results for weak types of singularities offer an unresolved contradiction.
