Research projects,




Since Jan. 2011, I help as adviser in Jana Roithovás ERC funded project ISORI. In less than 2 years, a new ion trap instrument has been developed. A description and first results can be found in [jas13].

The cooperation with Stephan Schlemmer includes Nano particle mass spectrometry (NPMS), trapped particles at low and high temperatures, and, since 2013, a new cooperation with Igor Savic (Novi Sad) on "H3+ at low and high temperatures (supported by the DFG).

On August, 06. 2009, the AB-22PT apparatus was moved from Chemnitz to Prague. This unique instrument combines a cold effusive beam (H atoms) with a temperature variable 22-pole ion trap. From the cooperation with the group of J. Glosik several joint publications appeared, e.g. H + H, H+ + H2 radiative association, and N+ + H2 originated. Planned projects include H+ + D, H + D, HeH+ + H and NH+ + H.

Quantum systems, virtually free from outside perturbations. Trapped atomic and molecular ions are at the heart of this revolution, providing the key to a deeper understanding.

The main objective of this action is to study chemical processes relevant to the physical conditions encountered in the inter- and circumstellar stellar medium
