Multielectron effects on single-electron strong field ionization

摘要: An apparently simple phenomenon of single-electron strong field ionization involves subtle factors related to multielectron effects. A single electron in an atom or molecule can feel a distinctly different screening strength when exposed fields as opposed weak fields, and this due motion influences ionization. The concept corresponding model developed the paper allow generalization Ammosov-Delone-Krainov for predicting rates more complicated atoms molecules. This general approach explains recently observed anomalous low rate O{sub 2} . (c) 2000 American Physical Society.
