Abstract
The authors have studied atomic hydrogen in intense, short, visible laser pulses (I6*1013 W cm-2) they observe a new series of higher order above-threshold ionization peaks in the photoelectron energy spectrum. They discuss some tentative explanations. Two models are described in some detail. One relies on ionization saturation, the second one may be named 'parking of atoms as Rydberg wavepackets'.Keywords
