Abstract

We present a theoretical description of the dynamics of vibrational wave packets in the 1g state of Xe2. As an illustration, a simulation of a picosecond pump excitation-probe ionization laser experiment is carried out. The initial wavepacket is calculated using an explicit modelling of the short-pulse excitation process and propagated for up to 160 picoseconds. Evidence of fractional and full revivals of the wavepacket has been found and analyzed. The time delayed ionization signal is simulated using first order perturbation theory and shows clear oscillations corresponding to the temporal development of the wavepacket.
Xe2 1g态振动波包动力学的理论研究
我们提出了Xe2在1g状态下振动波包动力学的理论描述。为了说明这一点,进行了皮秒泵浦激发探针电离激光实验的仿真。初始波包是使用短脉冲激励过程的显式建模计算的,传播时间可达160皮秒。发现并分析了波包部分和完全恢复的证据。时间延迟电离信号用一阶微扰理论进行了模拟,显示出与波包的时间发展相对应的清晰振荡。
