The Schroedinger equation for the singlet ground state of a system of the conduction electrons coupled with a localized spin by an antiferromagnetic s-d exchange interaction is solved in a closed form by collecting the most divergent terms in a perturbation series and the obtained wave function is investigated. In particular, it is shown that although the normalization integral for the ground-state wave function diverges with logarithmic accuracy, such physical quantities as the kinetic and potential parts of the energy, and the charge density can still be calculated with the use of this solution. It is concluded that the charge density originally accumulated around the localized spin spreads out uniformly and that the results obtained by the iteration method in the preceding papers remain essentially unchanged.
