โœฆ Synopsis


An investigation was made of scattering-amplitude expansions in functions characterized by the poles of the analytic continuation of the S-matrix elements in the complex angular plane. An analytical expression is given for the one pole contribution to the scattering ampEtude.

In this paper we describe a recursive procedure for the approximate evaluation of the coefficients of expansion of a function y(x) in a system of polynomials ~. ( ..~(x)1, kEN. Numerical examples and the computational procedure are also discussed.
