Abstract
Vapor pressures of argon—krypton mixtures at vanishingly small solid accumulation have been analyzed to give values of the interaction energy parameter wAB for a number of Ar–Kr solid solutions at temperatures between 85° and 101°K and in the argon mole-fraction range 4% to 18%. Vapor pressures and triple points of pure argon and krypton are also reported. The mole-fraction dependence of wAB is negligible, and compatible with that predicted by an exact form of the regular solution or Ising lattice problem.
