The system composed of Rydberg Li atom in an electric field is chaotic because of the core scattering. The period orbits and the closed orbits both exist near the saddle point. The dynamics of this system is studied with the closed-orbit-theory and Poincaré SOS method. The relations of the two methods are discussed for the first time and new information is obtained which can't be retrieved from the recurrence spectra.
