Atomic and Molecular Collisions Laboratory

Electron Transfer Processes in Biomolecular Systems Through Atom-Molecule Collisions

Research Group of Professor Paulo Limão-Vieira

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

 

We are also particularly interested on the complementary information obtained by this technique and comparisons with electron attachment experiments.
