Observation of continuum spin - orbit coupling inL-shell ionization of gold by polarized relativistic electrons

Abstract

The spin asymmetry associated with the ionization of the L shell of gold by 300 keV electrons polarized perpendicular to the scattering plane has been measured in an (e, 2e) coincidence experiment carried out in coplanar asymmetric geometry. The agreement with theoretical results obtained in the relativistic distorted wave Born approximation is favourable.

“…Recently, two types of relativistic (e, 2e) experiments using transversely polarized electron beams and unpolarized targets have been carried out to measure spin up-down asymmetries. In the first type, spin asymmetries have been measured on the K-shell of silver (Prinz et al 1995) and on the L-shell of gold (Prinz and Keller 1996). These asymmetries are caused by spindependent forces, i.e.…”
