    "abstract": "In conditions where the interaction betweeen an atom and a short\nhigh-frequency extreme ultraviolet laser pulse is a perturbation, we show that\na simple theoretical approach, based on Coulomb-Volkov-type states, can make\nreliable predictions for ionization. To avoid any additional approximation, we\nconsider here a standard case : the ionization of hydrogen atoms initially in\ntheir ground state. For any field parameter, we show that the method provides\naccurate energy spectra of ejected electrons, including many above threshold\nionization peaks, as long as the two following conditions are simultaneously\nfulfilled : (i) the photon energy is greater than or equal to the ionization\npotential ; (ii) the ionization process is not saturated. Thus, ionization of\natoms or molecules by the high order harmonic laser pulses which are generated\nat present may be addressed through this Coulomb-Volkov treatment.",
