Welcome to the Max-Planck-Institut für Kernphysik (MPIK, Max Planck Institute for Nuclear Physics) in Heidelberg, one of 84 institutes and research establishments of the  Max-Planck-Gesellschaft (Max Planck Society). The MPIK does experimental and theoretical basic research in the fields of Astroparticle Physics (crossroads of particle physics and astrophysics) and Quantum Dynamics (many-body dynamics of atoms and molecules).

Tracing the time of atomic processes


Physicists at the Max Planck Institute for Nuclear Physics (MPIK) in Heidelberg made an important contribution to the measurement of ultrashort atomic processes. This is based on the method of "attosecond streaking" of photoionization, which translates time differences into measurable differences in the speed of the photoelectrons. However, this requires a correction due to the electric interaction of the electron with the ion. Various theoretical models have now been experimentally tested and confirmed by the MPIK researchers.
