Opis

The Advanced Study Institute on "Photoionization and Other Probes of Many-Electron Interactions" was held at the Centre "Les Cigales" in Carry-Ie-Rouet (France), from August 31st till September 13th 1975. The Institute was sponsored by the Scienti- fic Affairs Division of NATO. The "Centre National de la Recher- che Scientifique" (France) gave also partial support to the French participants and the National Science Foundation (U. S . A. ) to the American participants. A total of 18 lecturers, and 54 students selected among more than 120 applicants, attended the Institute. Over the last few years, substantial progress has been made in the experimental study of photon- or electron interactions with atoms. In particular, the g. rowing number of facilities created to use the synchrotron radiation makes now possible the realization of new types of experiments. The accumulation of new results showed clearly it was necessary to introduce electron correlations in the theoretical models in order to explain the existence and the probability of a large number of processes, in particular multiple processes. Thus large progress has also been made in the theore- tical description of the excitation of the electronic systems and their interactions. It was the purpose of this Institute to bring together theoreticians and experimentalists in order to provide an opportunity to present in details the state of the art, in experiment as well as in theory, and to favor discussions on future experimen- tal and theoretical studies.
