Photoelectron holography and effects of the core potential — •Nikolay Shvetsov-Shilovski and Manfred Lein — Leibniz Universität Hannover, Hannover, Germany

Strong-field photoelectron holography (SFPH) is a new technique for time-resolved molecular imaging based on the interference of two types of outgoing electron trajectories in strong-field ionization [1]. Different subcycle interference structures were predicted within the semiclassical model accounting for the laser field only [2]. Although this model has provided valuable insight into the SFPH, neglecting the long-range Coulomb potential may be severe.

Using the two-step semiclassical model with interference [3] we investigate the modification of the interference structures due to the Coulomb potential and due to the choice of the initial state. Bearing in mind possible application of the SFPH to negative ions, we study holographic patterns in a short-range potential.
