Electron emission from H2+ in circularly polarized strong fields including nuclear motion or full electronic coordinate space — •Myroslav Zapukhlyak1, Jost Henkel1,2, and Manfred Lein11Institut für Theoretische Physik and Centre for Quantum Engineering and Space-Time Research (QUEST), Leibniz Universität Hannover, Appelstraße 2, 30167 Hannover, Germany — 2Institut für Physikalische und Theoretische Chemie and Röntgen Research Center for Complex Material Systems, Am Hubland, 97074 Würzburg, Germany

Inspired by recent work on strong field ionization of H2+ [Odenweller et al., PRL 107, 143004 (2011)] we show new quantum mechanical calculations on this molecular system in circularly polarized laser pulses. We extend previous calculations by including nuclear motion on the one hand and full three-dimensional electronic motion on the other hand. By doing so, we explore the coupled nuclear-electronic dynamics to find the most contributing nuclear distance. Regarding the anisotropy of electron emission from the fixed-in-space molecular ion, we gain additional information from the lateral width of the electronic momentum distribution, which gives depletion-insensitive information about system and laser pulse.
