A correction factor to the interatomic potential screening function for use in computer simulations

Abstract
The available data on the interatomic potential derived from ion-atom experiments is compared with two theoretical forms of the screened Coulomb interatomic potential. From these results a correction to the screening radius, involving a function of the atomic numbers of the collision partners, is derived. Application of this correction factor in computer simulation studies of ion-surface interaction should improve the accuracy of the ' simulations.
