The effect of n-H₂ impurity on the heat capacity of solid Ne
The alloy of Ne - 5.1%n-H₂ was investigated calorimetrically under equilibrium vapor pressure in an interval of 0.9–25 K. The magnitudes and the temperatures dependencies of the heat capacity Cso₁(T) of the alloy at T = 11–20 K are strongly dependent on the conditions of sample preparation. The temp...

The temperatures dependencies of the Cso₁(T) of the sample prepared in a calorimeter by direct condensation of a gas mixture at T = 15 K exhibit a smeared maximum near the triple point temperature of hydrogen and a phase transition at T = 17.1 K. The detected features of Cso₁(T) indicate that the preparation of the solid Ne – n-H₂ from a gas phase leads to the formation of a nonequilibrium long-living phase Ne with large H₂ concentrations and a small portion of H₂ inclusions with low Ne concentrations. The phase transition is caused by decompositions of this phase. The phase dose not recover on cooling the sample after the phase transition.
