In previous publications it has been shown that there exists a singlet bound state for a system consisting of conduction electrons and a localized spin coupled by an antiferromagnetic exchange interaction, and its binding energy has been calculated by a modified perturbation method. In this paper the structure of this modified perturbation method is analysed and it is shown in detail that the energy of the state containing the bound state is lower by the binding energy of the latter than that obtained by the usual perturbation method. The case of a localized spin whose magnitude is greater than one-half is also briefly discussed.
