Van der Waals Complexes in Supersonic Beams – Laser Spectroscopy of Neutral–Neutral Interactions

Jaroslaw Koperski studied Physics at the Jagiellonian University Krakow, Poland, and finished his PhD in 1989. Since then he works at the Jagiellonian University, presently as an Assistant Professor. He spent a few years at the University of Windsor, Canada, and the Commonwealth Scientific and Industry Research Organization in Melbourne, Australia. His main research interests are laser spectroscopy of van der Waals molecules produced in supersonic beams, elements for manipulation of ultra-cold atoms and atomic interferometry, as well as properties and application of quantum beats method in atomic and molecular spectroscopy.
