The optical potential is investigated for a chemically reactive system, K CH3I, with an assumed potential of interaction among the three species, K, I, CH3. The complex optical potential satisfies an integral equation with a kernel related to the solution of the threebody problem, as given by Faddeev. In order to obtain some information on the form of the optical potential without numerical analysis, a number of approximations are introduced. The imaginary part of the optical potential, which gives rise to absorption reactive and inelastic collisions, is with these approximations essentially a delta function of the KI distance. The real part of the optical potential is similar in form to the repulsive potential estimated from elastic scattering experiments on this system. Author
