Study of multiple ionization of Ne, Ar and Xe induced by intense XUV femtosecond laser pulse — •Roland Guichard, Myroslav Zapukhlyak, Ulf Saalmann, and Jan-Michael Rost — Max-Planck-Institut für Physik komplexer Systeme, Nöthnitzer Straße 38, 01187 Dresden, Germany

Recently, an experiment performed at FLASH in Hamburg showed that xenon atoms irradiated with intense XUV femtosecond laser pulses can be ionized up to Xe+21 [1]. In order to shed more light onto these processes, we have performed ab-inito calculations based on time-dependent density functional theory. Additionally, we present results on two less involved cases, namely Ne and Ar for which experimental data have also been recorded [2,3]. Taking into account the spatio-temporal pulse dependence is required for a reliable comparison of the experimental data with the theory.
