| Abstract: | The isotopic ordering of H2–D2 mixtures adsorbed at low temperature on graphite in the monolayer range is measured by small angle neutron scattering (SANS). We show that below 8 K, solid mixtures exhibit isotopic clustering at large density (monolayer completion) and a tendency towards the formation of ordered compounds for smaller density (near the commensurate structure). |
