中文摘要：
研究了电场中的里德堡态Li原子的动力学特征,虽然Li原子与H原子一样最外层都只有一个价电子，在远离核的地方电子的运动情况二者基本相同，由于原子实的存在，即使是能量很低时Li原子的哈密顿量也不能分离变量，因此在核区附近总是存在着混沌．利用Poincar6截面的方法比较了Li原子与H原子在动力学性质方面的不同，并进一步说明在外场中非H里德堡原子的光吸收回归谱中所出现新的共振峰可以归结为原子实的散射作用产生的组合轨道的效应．
英文摘要：
The dynamics of Rydberg Li atom in an electric field has been analyzed with the Poincare surface of sections method. It can be seen that the movement of active electron of Li and H are much dissimilar, although the numbers of the valence electron are same. The Hamiltonian of Li is inseparable and the nucleus of Li scatters the trajectory from one to another basic trajectory stochastically, and it can be interpreted by the chaos area around the nucleus in the Poincare surface of sections of Li. In contrast to that of hydrogen situation the Poincare surface of section is helpful to understand the appearance of the combined orbits and the new additional peaks in the recurrence spectra of Rydberg Li atom.
