Abstract : A number of aqueous systems including acids, bases and some organic materials were irradiated at 77 degrees K with a Co-60 gamma-source, and then investigated by ESR spectroscopy. Hydrogen atoms were found in sulfuric and hydrochloric acid solutions. In H2SO4, at low concentrations, the hydrogen atoms were quite stable at 77 degrees K. At higher concentrations there was a noticeable decrease after storage at 77 degrees K. Preliminary data indicate that hydrogen atoms are much less stable in HCl than in H2SO4. (Author)
