标题： Resonant two-photon single ionization of two atoms

摘要： 在由两个空间上充分分离的原子组成的系统中研究了共振双光子电离。 由于两中心电子-电子关联，电离也可能通过同时激发两个原子随后发生原子间库仑衰变来实现。 我们表明，这一通道可能主导光致电离过程，并定性地改变其对场强度和发射电子谱的依赖性。 显示英文摘要

摘要： Resonant two-photon ionization in a system consisting of two spatially well-separated atoms is studied. Due to two-center electron-electron correlations, the ionization may also proceed through photo-excitation of both atoms with subsequent interatomic Coulombic decay. We show that this channel may dominate the photoionization process and qualitatively change its dependence on the field intensity and the spectra of emitted electrons.
