Li2分子含时波包动力学的理论研究

利用含时量子波包方法计算得到了Li2分子的光电子能谱，并运用波包动力学理论对含有不同参量的光电子能谱现象给出了合理的解释。通过分析文中的直观图像，研究了波包的动力学过程。结果表明，泵浦-探测脉冲的延迟时间对光电子能谱的形状有重要的影响；在较短延迟时间下，能谱独特的四峰现象是由光诱导势的产生引起的。

Theoretical Investigation of the time-dependent wave packet dynamics of Li2 molecule

Time-dependent quantum wave packet method is performed to calculate the time-resolved photoelectron spectra (TRPES) of the Li2 molecule. The phenomena of PES corresponding to different parameters are interpreted reasonably by using wave packet dynamics theory. By analyzing intuitional images presented in this work, the dynamical process of wave packet is investigated. The investigation shows that the pump-probe delay time of laser pulses has significant influence on the shap of photoelectron spectrum. It also shows that the particular phenomenon of TRPES with four peaks at short delay time is induced by the appearance of light-induced potential (LIP).
