Popis: We describe in detail the evaluation of two-electron (1/ r 12 ) integrals for diatomic molecules for the case in which one orbital is a continuum function. The numerically oriented method employs a single center expansion of the bound molecular orbitals, which may be composed of either Slater or gaussian basis functions, around the origin of the Coulomb function. The accuracy and efficiency of the method is discussed.
