Abstract
Various refinements are added to a previous theoretical calculation of the configurational free energy of condensed mixtures of o- and p-hydrogen, based on an oversimplified statistical model: (a) account is taken of the fact that the forces acting between o- and p-molecules are somewhat different and (b) the rigid lattice model previously used is replaced by an ensemble of Einstein oscillators. A better agreement with experiment is reached.Keywords
