不同的初始态对氢原子电离率的影响

The Effects of Different Initial States on Ionization of Hydrogen Atom

采用二阶劈裂算子算法,数值求解了超短脉冲强激光场中一维模型氢原子的含时演化过程,得到了氢原子初始位于不同态时对应的电离率,结果显示当初始态为基态时,电离率总体不太大;而当初始态是激发态时,原子会被激光场迅速电离。

Using the ‘split operator＇ method, we numerically calculated the evolution of a one -dimensional model hydrogen atom interacting with intense ultra - short laser pulse. We concentrate upon the effect of using different initial states on the final ionization. We find that if initial state is in ground state the ionization probability is not large; while if initial state is in the excited states the electron is ionized rapidly.
