Intramolecular scattering: Simulation of coupled electron-nuclear motion upon photoionization — Friedrich Georg Fröbel, •Alexander Schubert, and Stefanie Gräfe — Friedrich-Schiller-Universität Jena, Jena, Germany.

We theoretically investigate intramolecular scattering and energy redistribution during photoionization of molecular systems in intense few-cycle XUV laser fields. The molecular model system is described by the extended Shin-Metiu model consisting of two position-fixed nuclei with one movable nucleus in between and two electrons in a single dimension. Dynamics simulations are performed by integrating the time-dependent Schrödinger equation numerically using grid-based methods. Spectral signatures in the photoelectron spectra are shown to contain sensitive information about different ionization pathways revealing the ionization-induced electron and nuclear dynamics and subsequent non-adiabatic effects.
