在相邻原子 B 存在的情况下,原子 A 的光电离可以通过 B 的共振激发进行,随后通过两中心电子-电子关联将能量转移到 A。我们证明,这种双中心机制在纳米核间距下可以远远优于直接光电离,并且在其时间发展和发射电子的光谱方面具有特征。
Photoionization of an atom A, in the presence of a neighboring atom B, can proceed via resonant excitation of B with subsequent energy transfer to A through two-center electron-electron correlation. We demonstrate that this two-center mechanism can strongly outperform direct photoionization at nanometer internuclear distances and possesses characteristic features in its time development and the spectrum of emitted electrons.
