用经典动力学和量子力学方法分别研究了Ｈ＋２在超短强激光场中的电离、离解和残存行为，得到了相似的结果：即在超短强激光脉冲作用下，Ｈ＋２的电离占优，但有限的量子计算低估了Ｈ＋２的离解几率；而经典处理则没有显示Ｈ＋２在超强场中的稳定化。另外，经典计算表明当核间距Ｒ伸展到一定范围时，Ｈ＋２的电离率最大。这符合量子计算中发现的电荷谐振增强电离（ＣＲＥＩ）现象。 The ionization, dissociation and residual behavior of H + 2 in the ultrashort strong laser field were studied by classical dynamics and quantum mechanics respectively. Similar results were obtained: the ionization of H + 2 dominated by ultrashort intense laser pulses, The limited quantum computation underestimated the probability of dissociation of H + 2; whereas the classical treatment did not show the stabilization of H + 2 in the super-field. In addition, classical calculations show that when the nuclear distance R extends to a certain extent, the ionization rate of H + 2 is the largest. This is in line with the charge-resonance-enhanced ionization (CREI) phenomenon found in quantum computing.
