Calculation of the non forward scattering amplitude for long range potentials

Abstract

The regularization factor technique is considered as a summation method for divergent, oscillating and slowly convergent partial wave expansions of the non-forward scattering amplitude for long range central potentials. Its convergence properties are studied and its efficiency is compared with that of the Punctual Padé approximant method in the cases of the Kratzer and Lennard-Jones potentials.
