Abstract
The mathematical methods involved in the evaluation of three‐body interactions between rare‐gas atoms or alkali‐halide ions with Gaussian type electron wavefunctions are outlined in first and second orders of perturbation theory. These methods are of general applicability for the analysis of many‐center coulombic and exchange integrals occurring in problems of atomic and solid‐state physics in which Gaussian functions can be used as a basis.Keywords
