Inversion of the total scattering cross section spectrum of the Li + Kr system

Abstract

The ambiguity in recent German references and the updated compilation of potential parameters requires re-analysis of Rothe's experimental data on the Li + Kr atomic scattering system. Modification of the Lennard-Jones (12, 6) potential was tested with different types of terms, before a method of direct test was applied to various parts of the interatomic potential. The best representation of the experimental data, which reduces the sum of squared error more than 80 % and is better than a recent calculation of the potential function containing seven parameters, has been discovered having a Morse function for the long-range, attractive branch of the potential.
