Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Structure of quench condensed nH₂–N₂ alloys was investigated by powder x-ray diffraction over a wide
range of temperatures, compositions, and rates of deposition. The structure of the deposits is shown to depend
on the condensation regime. Under mild regime, no solid nitrogen reflections from hydrogen-rich deposits
were observed. When the temperature is increased to the hydrogen triple point, nitrogen lines appear
at substantially larger angles compared to pure N₂, which suggests presence of dissolved hydrogen. The
quantum nature of this hydrogen is suppressed in the nitrogen matrix. The samples grown in mild regime exhibit
the highest apparent solubility (up to 25%) of hydrogen in solid N₂. When H₂ is substituted by D₂, the
isotope effect consists in a wider range of mono-phase states based on the nitrogen cubic lattice, which can
accommodate up to 70% of deuterium, if grown under mild regime. |
