核间距对氢分子双电离的影响

Influence of Internuclear Distance on Double Ionization of H_2

本文利用经典三维系综模型,研究了超强线偏振激光作用下核间距对氢分子双电离的影响。结果表明,氢分子双电离率随核间距变化。随着核间距的增大,氢分子双电离率先增大,后减小,在R=4 a.u.时取得最大值。

Using three - dimensional classical ensembles, we investigate the influence of the internuclear distance R on double ionization of H2 molecules driven by an intense laser pulse. We find that double ionization probability of H2 molecules changes with R. As R increases, double ionization probability first increases, then decreases, and reaches a maximum at R = 4a. u.
