TL;DR: The phenomenon of multiply-excited states in beam-foil spectroscopy has been studied in this article, where a review of the early B.F.S. work is presented.
Abstract: The phenomenon of the excitation of multiply-excited states in beam-foil spectroscopy is reviewed: 1. Introduction, early B.F.S. work. 2. (a) Earlier non-beam-foil observations of multiply-excited states; (b) Theoretical development of multiply-excited systems; (c) Experiments and theory since 1961. 3. B.F.S. photon measurements: (a) He I isoelectronic sequence. (b) Li I isoelectronic sequence. (c) Be I and heavier isoelectronic sequences. (d) Transition probabilities, comparison of theory and experiment. 4. B.F.S. electron measurements. 5. The beam-foil interaction process. 6. Present problems and future aspects.
