Abstract :Two-center kinetic energy and nuclear attraction integrals are defined in terms o f overlap integrals and incomplete gamma functions. A new analytical expression is obtained for nuclear attraction integral V(c> where the nuclear attraction operatör is not located at the same çenter with the basis functions. The recursive relations and generalized binomial coefficients are used for the evaluation of these integrals. Computer results are in good agreements with values given in the literatüre.Keywords : Calculations, two-center, integrals
