Low-energy electron ion recombination in a magnetic field — •Maria Hörndl, Shuhei Yoshida, Karoly Tokesi, and Joachim Burgdörfer — Institute for Theoretical Physics, Vienna University of Technology Wiedner Hauptstr. 8-10, A-1040 Vienna, Austria

The electron-ion recombination in cold magnetized plasmas is currently intensively studied both experimentally and theoretically. Recent storage ring experiments show a dramatic enhancement of the radiative recombination rate for high Z ions relative to what standard radiative recombination rates predict. We analyze the role of classical chaotic dynamics and unstable periodic orbits which bring an electron to multiple visits to the target ion and enhance the recombination. In addition, a role of stochastic perturbations in the dilute electron gas will be considered. This work is supported by FWF and SFB016.
