We explore a new field of laser-matter interaction. With the advent of novel intense laser sources at short wavelengths it becomes possible to drive so-called non-adiabatic transitions, that are very different from the well-known photo-effect. Most interestingly, they rely on the time derivate of envelope of the laser pulse. Those transitions where predicted theoretically and will be investigated in this project. We aim for a deeper understanding and a possible control of these transitions, ultimately proposing an experiment which will prove this new phenomenon.
