The Dynamical Properties Of Rydberg H And Li Near A Metal Surface

Recently much attention is focused on the motion of Rydberg atom near a metal.Because it is another important theoretical model and it could produce easurable experimental effect. In this model the atom-wall distance and energy of system play a critical role in the dynamical properties of the system.In this paper, the dynamical properties of Rydberg hydrogen atom and Lithium atom near a metal surface are studied by using of the methods of phase space analysis and closed orbit theory.The main work is given as fellow.(1)The theoretical model and the physical picture of the Rydberg atom near a metal surfaceare is introduced,and the scaled property of the system is described.(2) the atom-wall distance is 1000 Bohr radius,and Poincarémaps of Rydberg hydrogen atom and Lithium atom are plotted. It's found that the dynamical behavior of the system depend sensitively on energy. Through comparing the Poincarésections of Rydberg hydrogen atom and Lithium atom , the effect of the atoms reality is found(3) Let the system in external field of Z direction,and the atom-wall distance d is 1000 Bohr radius. Based on analyzing the Poincarésections of Rydberg hydrogen atom in external field it's found that the system dynamics behavior is dependent not only on energy parameters but also field intensity parameters(4) By using closed orbit theory, the periodic orbits of Rydberg hydrogen atom and Lithium atom are calculated to also find the influence of the atoms reality...
