Radiation damping of three atoms in a radiation field is studied for both a linear and closed‐chain configuration. One atom of the system is initially excited. Use is made of the Heitler‐Ma perturbation procedure up to second order. The discussion is developed in terms of the symmetry of the interactions within the system. The interactions arising from dipole transitions perpendicular to the plane of the closed chain are shown to be similar to the interactions in a two‐atom system, and the results are extended to cover larger rings.
