论文摘要
我们报告了运动学上完成的测量和从头静脉静止的计算，将He和H2的双电离计算通过单个800 EV圆形极化光子进行。我们确认了H2的光电离子化机制，并显示了它是如何起源于两电子靶标的两电子尖源的。我们的方法建立了一种新的方法，用于绘制电子相对于彼此的映射，并为电动偶极近似以外的光电离提供有价值的见解。
We report on kinematically complete measurements and ab initio non-perturbative calculations of double ionization of He and H2 by a single 800 eV circularly polarized photon. We confirm the quasifree mechanism of photoionization for H2 and show how it originates from the two-electron cusp in the ground state of a two-electron target. Our approach establishes a new method for mapping electrons relative to each other and provides valuable insight into photoionization beyond the electric-dipole approximation.
