Abstract : Techniques and data developed during previous studies of the ground state hyperfine resonance of hydrogen atoms intermittently adsorbed on molecular hydrogen surfaces are applied to the development of a Very Low Temperature Atomic Hydrogen Maser incorporating a state-selected hydrogen atom beam with thermal speeds near 5 K. Studies are made of adsorption of hydrogen atoms on molecular hydrogen and atomic neon solid surfaces at 4 K to 12 K. (Author)
