Breakdown of the independent electron approximation in sequential double ionization
(2011)New Journal of PhysicsCorrelated electron emission in strong field double ionization is dominated by recollision of the first ionized electron with its parent ion. With laser pulses that are close-to-circularly polarized, recollision may be greatly modified or avoided and the electrons are usually assumed to be field ionized without mutual interaction. Here, we present coincidence momentum measurements of the doubly charged ion and the two electrons, which are ...Journal Article
