Atomic and Molecular Physics Group, Institute of Experimental Physics I

Justus Liebig University, Giessen

The Atomic and Molecular Physics Group at the Justus Liebig University Giessen specializes in the physics of atomic collisions. The research covers fundamental questions of atomic and molecular structure and collision dynamics as well as applications in atomic and molecular spectroscopy, astrophysics, and plasma physics. The group develops electron and ion sources and performs experiments with charged particle beams (electrons, highly charged ions, molecular ions, cluster ions) at an in house electron-ion crossed-beams setup, at the ion storage rings at FAIR/GSI, at the Heidelberg cryogenic storage ring CSR, and at the Hamburg synchrotron light source PETRA III.
