## A bstrart Short range portions of two-center Coulomb functions at positive energies are decisive to evaluate the various wansition matrix elements between ionization continua and bound states. A method to represent them in terms of Gaussian functions is developed here. This enables us to effect
## Abstract Formulas can be automatically generated for all two‐center Coulomb integrals over Slater‐type orbitals by means of the “__C__‐matrix” single‐center expansion method with use of “computer algebra.” The formula coefficients may be stored in two‐dimensional arrays.
## Abstract For the general two‐electron two‐center integral over Slater functions, use of the Neumann expansion for the electron‐electron interaction term yields the standard auxiliary functions. These are expanded and integrated explicitly by two independent methods. The resulting simple analytic
