中文摘要：

运用半经典理论和静电成像的方法,首次对里德堡氢原子在静电场和金属表面附近的光电离显微进行了研究.首先根据静电成像的方法给出了体系的哈密度量,并且推导出了电子几率密度的计算公式.研究结果表明：由于金属面和静电场的共同作用,有多条从原子出发的电子轨迹会到达探测平面上一点处,由于电子波之间的干涉,放置在垂直于电场平面上的探测器将探测到一系列电子几率密度的振荡干涉图样.电子几率密度的振荡干涉图样敏感地依赖于标度电场和体系的标度能量变化.不同类型的电子运动轨迹对电子几率密度有不同程度的贡献.这些计算结果对未来实验上研究里德堡原子在外场和表面附近的光电离显微可以提供一定的参考价值.

英文摘要：

The photoionization microscopy of the Rydberg hydrogen atom in a static electric field near a metal surface has been studied on the basis of a semiclassical theory combined with the electric image method for the first time. Firstly,we put forward the Hamiltonian of the system according to the electric image method,then we derive the formula for calculating the electron probability probability. Our calculation results suggest that due to the combined effect of both the metal surface and static electric field,various electron trajectories emitted from the atom will arrive at a given point on the detector plane. Due to the interference between the electron waves,a series of oscillatory patterns in the electron probability density distributions will be observed on a position-sensitive detector placed in the plane perpendicular to the electric field. The oscillatory pattern in the electron probability density distributions depend sensitively on the scaled energy and the scaled electric field. Different types of electron trajectories will have different contribution to the electron probability density distribution. Our results can be used to guide the future experimental research on the photoionization microscopy of the Rydberg atom in the external fields near a surface.
