Stabilization of high-density atomic hydrogen in H-2 films at T < 0.5 K Academic Article uri icon


  • The stabilization of high densities of atomic hydrogen (2 1019 cm-3) embedded in solid H2 films has been achieved by employing a method for producing the samples involving a direct dissociation of H2 molecules by a cold plasma discharge in the sample cell at temperatures below 0.5 K. High stabilities against recombination were obtained. We observed density-dependent shifts and widths of the electron spin resonance lines resulting from the dipolar interactions between like and unlike spins. We discuss the possibilities for further increasing the H density and studying possible supersolid behavior. 2009 The American Physical Society.
