Resonances in few-body systems: proceedings of the International Workshop, Sárospatak, Hungary, Septermber 4-8, 2000 / edited by A.T. Kruppa and R.G. Lovas

Few-body resonances are in the frontiers of resonance studies. Very similar problems occur in atomic and molecular physics, nuclear physics and high-energy physics. This collection presents the state of the art of the studies of resonance states in these fields and demonstrates their common methodological aspects. Most of the contributions are theoretical, but quite a few are closely linked with experiments through the data they are dealing with.
