Ii. Guseinov et al., COMPUTATION OF OVERLAP INTEGRALS OVER SLATER-TYPE ORBITALS USING AUXILIARY FUNCTIONS, International journal of quantum chemistry, 67(4), 1998, pp. 199-204
Analytical expressions through the binomial coefficients and recursive
relations are derived for the expansion coefficients of overlap integ
rals in terms of a product of well-known auxiliary functions A(k) and
B-k. These formulas are especially useful for the calculation of overl
ap integrals for large quantum numbers. Accuracy of the computer resul
ts is satisfactory for the values of quantum numbers up to 50 and for
the arbitrary values of screening constants of atomic orbitals and int
ernuclear distances. (C) 1998 John Wiley & Sons, Inc.
