An electron system coupled with a localized spin is investigated. The spin non-flip part of the transition matrix (t-matrix) is expressed in terms of Green functions of spin operators. From an equation of motion for the latter an integral equation for the t-matrix is derived, which is nothing but the Nagaoka-Hamann equation. The equation is derived under the assumption that one-particle intermediate states play important roles.
