| 摘 要： | 将激光感生碰撞电荷看作一个四体系统，发展了激光感生碰撞电荷电荷的微扰理论，以独立原子和离子的复合态波函数作为激光感生碰撞体系的基组函数，得到了体系态振幅的运动方程。利用激光感生碰撞电荷交换的微扰理论，对Ｃａ＾＋－Ｓｒ间激光感生碰撞电荷交换进行了数值计算，并与Ｇｒｅｅｎ等人的实验结果进行了比较。

| Abstract: | The perturbative theory of laser induced collisional charge exchange (LICCE) is presented, in which the laser induced collisional charge exchange is described as a four body system and the compound atomic and ionic states are used as basis states of LICCE, and the equation of motion for the probability amplitudes of the states are obtained. The numerical results of LICCE in Ca + Sr are obtained for the first time through numerical calculation, and the comparison between the theoretical results and the experimental one (obtained by W. R. Green et al.) confirms the interpretation of the peaks at 477.0 nm as due to LICCE in Ca + Sr and the peaks at 471.5 nm due to LICET in Ca Sr system. |
