Breakdown of the independent electron approximation in sequential double ionization
Breakdown of the independent electron approximation in sequential double ionization is a scholarly work by Ursula Keller and Reinhard Dörner, published in 2011 in ''New Journal of Physics''. The main subjects of the publication include physics, atomic physics, ionization, attophysics, Double ionization, ion, momentum, electron, low-energy electron diffraction, and field. The authors present coincidence momentum measurements of the doubly charged ion and the two electrons, which are in disagreement with the independent electron assumption for close-to-circularly polarized fields.
