Atomic Hydrogen Maser Investigations of Hydrogen Atom Interactions from 4 K to 12 K.

Abstract

Techniques developed during previous studies of the ground state hyperfine resonance of hydrogen atoms intermittently adsorbed on molecular hydrogen surfaces were used to develop a cryogenic atomic hydrogen maser using a 5 K state-selected H atom beam and solid neon storage surfaces near 10 K temperature. The physical parameters affecting the use of such a device for frequency metrology and precision measurements of atomic parameters were determined. Keywords: Resonance; Cryogenic; Maser; Frequency metrology; Surface adsorption; Solid neon; Solid hydrogen.
