本文采用激光短脉冲激发磁场中氢原子,研究氢里德堡波包在磁场中随时间的演化。结果证实氢里德堡波包在磁场中的运动也与闭合轨道密切相关。讨论了脉冲宽度τ对自动关联函数的影响以及不同初始态下的自动关联函数。
A Gaussian short-pulse laser is applied to excited hydrogen atom in a static magnetic field and to produce Rydberg wave packets. We study the temporal evolution of Hydrogen Rydberg wave packets. Calculation shows in detail that the motion of hydrogen Rydberg wave packets is closely associated with semi-classical closed-orbit. We analyzed the autoeorrelation function and discussed the dependence of the autocorrelation function on the different initial states and the widths of the laser pulse.
