Abstract :An exact solution to the quartic equation in the wiggler frequency ww, which represents the dispersion relation for this system, is obtained. The effects of the frequency of the wiggler ww on the electron`s velocities insert ignore into journalissuearticles values(v\vert \vert and vw); are investigated. The regions of interest for the allowed wiggler frequency ww for both group I and group II electron trajectories are discussed.
