Photoionization sequences of multi-ionic neon — •Bernd Lohmann1,2, Ulrich Kleiman3, Markus Braune2, Axel Reinköster2, Burkhard Langer4, and Uwe Becker2 — 1Institut für Theoretische Physik, Universität Münster, 48149 Münster — 2Fritz-Haber-Institut der MPG, 14195 Berlin — 3MPI für Physik Komplexer Systeme, 01187 Dresden — 4MBI für Nichtlineare Optik und Kurzzeitspektroskopie, 12489 Berlin
The thriving results currently emerging from the free electron laser FLASH for the multi-photoionization of ions require for a theoretical interpretation. In a first attempt, we are employing the semi-relativistic Hartree-Fock code of Cowan [1] combined with the schemes of Racah algebra and fractional parentage [2], in order to relate the open-shell dipole transition matrix elements with the one electron dipole matrix elements provided by the Cowan code. First numerical cross section results for selected ionic photoionization sequences of neon will be presented.
