Abstract
PHOTOIONIZATION OF ATOMS, MOLECULES AND CLUSTER: FROM ENERGETICS TO DYNAMICS WITH NOVEL VUV LIGHT SOURCES The flux and energy resolution achievable at third generation facilities, like the Gas Phase Photoemission beamline of the Elettra storage ring (Trieste, Italy), has enabled for almost 20 years thorough photoionization studies of isolated systems, even with low density targets such as vapours of biomolecules [2] and clusters [3]. More recently, in stead, the interest of the atomic and molecular physics community has been attracted by the opportunity of exploring the temporal dynamics of isolated systems by means of novel state-of-the-art light sources. For this purpose two new beamlines capable of delivering ultrafast VUV photon pulses are currently under commissioning in the framework of the FERMI@Elettra Free Electron Laser (FEL) project: the Low Density Matter beamline at FERMI [4] and CITIUS [5], a state-of-the-art fs-VUV source, based on laser High Harmonic Generation on rare gases. Recent experiments on photoionization spectroscopy of gas phase molecular targets of increasing complexity will be presented, as well as research opportunities opened in the field of atomic, molecular and cluster physics by these novel ultrafast light sources.
