Experimental atomic physics

The Experimental atomic physics group investigates the fundamental properties of negative ions and we develop mass spectroscopic techniques. Please visit the pages below to learn more about our research, teaching and outreach activities.

 

Research highlight

Real-time observation of electron motion in the ground state of the carbon atom. A wave packet is created in the ground triplet state of the carbon atom via photodetachment of its negative ion in a strong laser field. Its dynamics is probed using the selectivity of strong-field ionization to orbital alignment in combination with an electron-imaging technique. A strong temporal modulation in the photoelectron yield at high kinetic energies along the vertically aligned polarization axis is observed, which reveals a periodic motion of the electron cloud in the atom (Hultgren et al. PRA 87, 031404(R) (2013)

The picture shows three images observed at time delays of 2000fs, 2300fs and 2600fs between the pump and probe beams. Here you can see a movie-clip of the pictures
