General numerical algorithm for classical collision integral calculation

A new automatic algorithm to calculate collision integrals from isotropic interaction potentials has been developed. The proposed method overcomes the limits of existing codes that need a priori definition of potential features. The algorithm efficiency has been tested by comparison with traditional approaches. The agreement achieved in reproducing published data is good. A theoretical analysis of the asymptotic behaviors, related to the accuracy of integral evaluation with respect to interval finiteness, is also reported. (c) 2008 Elsevier B.V. All rights reserved.
