- Аннотация: A quantum mechanical model for laser-assisted Auger decay based on the numerical solution of a system of non-stationary Schrodinger equations is developed. The model is applied to a particular case of Ne KLL Auger transitions. The effect of an intense laser field on the angle-resolved spectra of Auger electrons generated by ultrashort (subfemtosecond) pulses is investigated. We demonstrate that for energetic Auger electrons the sideband structure, which appears due to interaction of electrons with the strong laser field, does not correspond to the generally accepted picture of regular equidistant peaks separated by the laser photon energy. Moreover, the structure strongly depends on the observation angle. The origin of this phenomenon is discussed, and it is demonstrated that the standard sideband picture appears after integration over all angles. The described structure can provide a useful tool for controlling the phase of the x-ray pulse relative to the laser pulse in laser-assisted Auger emission experiments.
