Experiments with Polarized Electrons

Part of the NATO ASI Series book series (NSSB, volume 196)

Abstract

The focus of this seminar is on the atomic dynamics information which can be extracted from experiments with spin-polarized electron beams. The definition of electron polarization is given in Fig. 1. Since investigations with polarized electrons have been stimulated by advances of the experimental techniques in the past few years, the seminar will start with a brief outline of the state of the experimental art. A breakthrough was the GaAs source of polarized electrons. Polarizations of 35–40% with currents of a few μA are produced with it in several laboratories. The progress with polarized electron sources is, however, not matched by that with polarization analyzers.
