    "abstract": "The ionization of a one-dimensional model Helium atom in short laser pulses\nusing time-dependent density functional theory is investigated. We calculate\nionization probabilities as a function of laser intensity by approximating the\ncorrelation function of the system adiabatically with an explicit dependence on\nthe fractional number of bound electrons. For the correlation potential we take\nthe derivative discontinuity at integer numbers of bound electrons explicitly\ninto account. This approach reproduces ionization probabilities from the\nsolution of the time-dependent Schroedinger equation, in particular the\nso-called \"knee\" due to nonsequential ionization.",
