Research Interests

Over the last years I have been deeply involved in low energy electron (LEE) interactions leading to negative ion formation via dissociative electron attachment (DEA) or electron ionisation (EI), electron scattering processes from isolated molecules, electron transfer in neutral potassium collisions with gas phase isolated targets and VUV spectroscopy studies. DEA and EI studies are carried out in close collaboration with the universities of Innsbruck, Siedlce and Iceland. I projected and assembled a crossed electron molecule beam apparatus. This set-up consists of a trochoidal electron monochromator with electron energy resolution of about 100meV coupled with a reflectron time-of-flight mass spectrometer.
