Özet

This paper presents a computationally efficient formula in terms of basic overlap integrals over Slater type orbitals (STOs) for the evaluation of auxiliary function G(-ns)(q) which plays a central role in calculations of multicenter molecular integrals. The basic overlap integrals are calculated with the help of recurrence relations. The resulting simple analytical formula for the auxiliary function G(-ns)(q) (p(a), p, pt) is completely general for p(a) <= 1.2 and arbitrary values of parameters p and pt. The efficiency of calculation of auxiliary function G(-ns)(q) is compared with other method.
