论文摘要
众所周知，由两中心电子偶极偶极相关驱动的原子间或分子间相互作用随着位点间距离迅速掉落。但是，我们表明，由共振场触发的原子间反应通道的有效强度可以表现出非单调的距离依赖性，当原子靠近时会大大降低。通过将谐音的两中性光电离作为一个例子，证明了这一令人惊讶的结果。我们的发现得到了可用的实验数据的支持。
It is well known that interatomic or intermolecular interactions driven by two-center electronic dipole-dipole correlations fall off rapidly with the inter-site distance. We show, however, that the effective strength of interatomic reaction channels, which are triggered by a resonant field, can exhibit a nonmonotonous distance dependence, being strongly reduced when the atoms come closer. This surprising result is demonstrated by considering resonant two-center photoionization as an example. Our findings are supported by available experimental data.
