The spectroscopic properties of the ionic beam source.
A relatively new spectroscopic source, consisting of a beam of high velocity, unidirectional and monoenergetic atoms and ions that have been electronically excited by a thin foil, is described. Special attention is directed toward the properties of spectroscopic interest; some of these properties include particle densities, source purity, operating parameters, and the nature of the radiation emitted. The application of the source to the study of atomic excited state lifetimes is described with specific emphasis on the techniques of obtaining quantitative data using spectrometers, photomultipliers, and interference filters Also included is a complete bibliography of work done up to the present date.
