Indirect optical orientation of atoms in He–Cs gas discharge plasma: an explanation of anomalous ratio of the magnetic resonance signals

Abstract

This paper discusses the indirect orientation of Cs atoms, which was observed for the first time in our early works in a helium–cesium plasma discharge with use of an indirect registration method. We propose an explanation for the unusually small ratio of the magnetic resonance signals from Cs and metastable He atoms under condition of optical orientation of He atoms.
