A simple method for the rppro.ximation of three-center nuclear attraction integrals is given. In (x,ll/r,lx$ the point charge is expanded aroung the center 6. For the terms of the expansion in the potential a suitable appro.xbnation is used such that the integral is reduced to overlap-type integrals
