Atomic and Molecular Reactions in Slow-Motion — •Robert Moshammer — Max-Planck-Institut für Kernphysik, Heidelberg — Laureate of the Robert-Wichard-Pohl-Prize

Many-particle spectrometers (COLTRIMS / Reaction-Microscopes) combined with modern short-pulse IR and XUV radiation sources offer new prospects for studies of ultra-fast processes in atoms and molecules. At present, due to the enormous advances in laser technology, light pulses with durations of only a few femtoseconds (5 fs) down to the attosecond regime are available at intensities of 10¹⁴ W/cm² or more, revealing insight into the coupling of light with matter. How does an atom absorb two or more photons from an intense laser pulse, and how is the energy released after the interaction? This and other fundamental processes are subject of ongoing research. Pump-probe experiments with molecules allow the observation of rotational, vibrational and electronic excitations with unprecedented resolution and in real time, and time-resolved experiments with molecules using intense fs XUV Laser pulses are very first steps towards the visualization of fundamental molecular reactions. The general physical and technical concepts will be discussed and recent results will be presented.
