• The theory of the singlet ground state for an s-d interacting system developed in the most divergent approximation is extended so as to include the next divergent contributions. With the aid of the renormalization group theory all the corrections are evaluated in a closed form to a secular integral equation for the wave functions. The solution gives the binding energy E^〜=-Dexp{(N/Jρ)[1+(Jρ/2N)log|Jρ/2N|]} where the correction cannot be simply expanded in a power series with respect to J but is relatively small compared to the most divergent result.
