用准自由双光电离揭示He和H2基态的双电子尖点
Revealing the Two-Electron Cusp in the Ground States of He and H2 via Quasifree Double Photoionization
摘要：
我们报告的运动学完整的测量和从头算非微扰计算的双电离的He和H2由一个单一的800 eV的圆偏振光子。我们证实了H2光电离的准自由机制，并说明了它是如何起源于双电子靶的基态中的双电子尖点的。我们的方法建立了一个新的方法映射电子相对于彼此，并提供了宝贵的洞察光电离超越电偶极子近似。
英文摘要：
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.
