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.
