[en] An approximation scheme is given which simplifies considerably the calculation of nuclear interaction energies between two deformed nuclei whose sharp surfaces are non-over-lapping. For energies calculated as the Yukawa interaction between two nuclear distributions generated by folding short ranged Yukawa functions, the approximation gives results which are in good agreement with the exact results over a wide range of masses and spheroidal deformations of the two nuclei.
