摘要：
An ENDOR spectrum of H atoms produced in the gamma-ray irradiated solid H-2 was measured at 4.2 K in order to elucidate the structure of the local environment of the H atoms in solid H-2. We found that the H atoms were not trapped in interstitial sites but in substitutional sites of the solid, and almost all the ortho-H(2 )molecules at the first nearest sites from the H atoms converted into para-H-2 molecules. This result shows that the ortho-para conversion is induced by electron spins of the H atoms. (C) 1998 Elsevier Science B.V. All rights reserved.
