Cross section statistics for non-hydrogenic Rydberg atoms in crossed fields — •Javier Madroñero1, Thomas Gorin2, Shinosuke Kawai3, and Andreas Buchleitner2 — 1Physic Department, Technische Universität München, München — 2Max-Planck-Institut für Physik komplexer Systeme, Dresden — 3Laboratoire de Chimie Theorique, Faculte des Sciences, Universite de Sherbrooke, Quebec, Canada
Fluctuations of the ionization cross section for non-hydrogenic Rydberg atoms in crossed electric and magnetic fields are considered in a regime where the classical dynamics is dominated by chaotic scattering and the quantum mechanical regime shows strongly overlapping resonances. Classical decay rates are computed by direct Monte-Carlo methods as well as transition state theory, and compared with numerically exact quantum simulations.
