摘要
文中应用扩展的半经典闭合轨道理论计算了Li原子在平行电磁场加一个振荡电场中的回归谱。与相同情况下平行电磁场中的回归谱比较,当附加含时振荡场时,静外场中的吸收光谱的强度被很大程度地减弱。另外,分别讨论了回归谱强度随振荡场振幅以及频率的变化规律。
Using a extending semi-classical closed-orbit theory, we calculated the time-dependent recurrence spectra of Li Rydberg atom in the parallel electric and magnetic field plus an oscillating electric field. We have also compared the results with that one of absence of the oscillating field. Our studies show that when the time-dependent field was applied, the recurrence strength was weakened greatly in a complex pattern. In addition, we analyzed in detail the change of recurrence strength as the functions of the amplitude and oscillating frequency, respectively.
