STUDY OF STABILIZATION OF HYDROGEN ATOMS AT 77 DEGREES K AND HIGHER TEMPERATURES.

Abstract

A number of aqueous solutions of inorganic and organic materials were irradiated at 77K with Co-60 gamma rays and then examined by ESR spectroscopy. H-atoms in H2SO4 and H3PO4 were found to decay rapidly during the first 20 to 30 hours after irradiation. In 0.13 mole fraction HClO4 solutions the H-atoms were stable at 77K. At higher temperatures the decay consists of two simultaneous first-order reactions. H-atoms were also found on a number of silica and silica-alumina adsorbents. Detailed decay studies were made for H-atoms on a water-loaded molecular sieve. The H-atoms decay with second-order kinetics for samples prepared and irradiated in the presence of air samples were also prepared in the absence of air. (Author)
