Influence of an orthodeuterium impurity on the thermal conductivity of solid parahydrogen

Influence of an orthodeuterium impurity on the thermal conductivity of solid parahydrogen

The thermal conductivity of solid parahydrogen with orthodeuterium impurity at the impurity concentration from 0.01 to 1% has been studied in the temperature range from 1.8 to 9 K. The nonlinear concentration dependence of the thermal resistivity of the investigated samples is explained by the fact...
