摘要
利用闭合轨道理论和Poincar截面两种方法研究了鞍点附近电场中高里德伯态Li原子的动力学性质.由于原子实的作用,体系是混沌的,闭合轨道和周期轨道在混沌体系中并存,但二者在Poincar截面上的反映是不同的.讨论了两种半经典理论在研究混沌体系时的联系,得到了仅靠闭合轨道理论得不到的信息.
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.
