We report on electron spin resonance studies of H atoms stabilized in solid Hfilms at temperature 0.7 K and in a magnetic field of 4.6 T. The H atoms were produced by bombarding Hfilms with 100 eV electrons from a radiofrequency discharge run in the sample cell. We observed a one order of magnitude faster H atom accumulation in the films made of para-Hgas with a small ortho-Hconcentration (0.2% ortho-H) as compared with those made from normal Hgas content (75% ortho-H). We also studied the influence of ortho-Hmolecules on spatial diffusion of H atoms in solid Hfilms. The spatial diffusion of H atoms in both normal and para-Hfilms is faster than the diffusion obtained from the measurement of H atom recombination. The rate of spatial diffusion of H atoms in para-Hfilms was slower in comparison with that in the normal Hfilms. We discuss possible explanations of these observations.
