# Multistate molecular treatment of atomic collisions in the impact parameter approximation. IV

## Description

Abstract We propose a new version of the program PAMPA with increased efficacy for large systems of coupled equations. The organisation of the present version is better suited to vector processors. The method used to calculate the integrals over energy differences takes full advantage of the spline representation used for the energies, which increases its accuracy.
