General Physics Colloquium Wed. 13 May 15:15-16:00 Fys Aud. Title: When time scales disappear in your storage ring Speaker: Klavs Hansen, University of Gothenburg / IFA Abstract: Storage rings have opened for a wealth of new experiments on molecules, clusters and atoms. The combination of extremely good vacuum, good detection efficiency and laser excitation have pushed the edges of feasibility. One of the effects that was seen soon after the first electrostatic ring, ELISA, was commisioned here in Aarhus was the disappearance of time scales in experiments on clusters and molecules. In the talk I will explain where they went, what they revealed when they left, and what we understood when they boomeranged back
