Two-Center Integrals for r_{ij}^{n} Polynomial Correlated Wave Functions

arXiv:1104.3646 · doi:10.1103/PhysRevA.3.1581

Abstract

All integrals needed to evaluate the correlated wave functions with polynomial terms of inter-electronic distance are included. For this form of the wave function, the integrals needed can be expressed as a product of integrals involving at most four electrons.
