| Abstract: | An algorithm for evaluation of two‐center, three‐electron integrals with the correlation factors of the type r r and r r r as well as four‐electron integrals with the correlation factors r r r and r r r in the Slater basis is presented. This problem has been solved here in elliptical coordinates, using the generalized and modified form of the Neumann expansion of the interelectronic distance function r for k ≥ ?1. Some numerical results are also included. © 2003 Wiley Periodicals, Inc. Int J Quantum Chem, 2004 |
