EVALUATION OF RELATIVISTIC ATOMIC INTEGRALS USING PERIMETRIC COORDINATES

摘要

Calais and Lowdin developed a simple method using the interelectronic distance as an integration variable to treat two-electron integrals occurring in correlated nonrelativistic atomic calculations. This contribution merges their method with a related one to further evaluate two-body integrals occurring in relativistic configuration interaction calculations. (C) 1997 John Wiley & Sons, Inc.
