Electron Transfer Processes in Atom-Molecule Collisions

High Resolution Electron Energy Loss Spectroscopy

He(I) Photoelectron Spectroscopy

 

The main research goals are the study of the dynamics of negative ions formed by charge transfer in atom-molecule collisions, with the special attention to biomolecular systems. We make use of a crossed molecular beam machine, where a neutral hyperthermal potassium beam (Ko) crosses at right angles an effusive molecular target and the negative ions formed in the interaction region are TOF mass analysed;

 

We look at the electronic state spectroscopy of gas-phase molecular targets in dipolar and non-dipolar conditions in a High Resolution Electron Energy Loss Spectroscopy (HREELS) setup;

 

We are currently setting up a He(I) Photoelectron Spectroscopy (PES) machine for probing low lying ionic states in molecular targets.
