Orientational ordering in molecular hydrogen. IV. Phase transition of the second kind in the hexagonal lattice
Abstract
The orientational ordering in rigid orthohydrogea and paradeuterium with hcp lattice is
investigated by the method of the theory of bifurcation of the solutions of nonlinear
integral equations. It is shown that in the average field approximation there is a phase transition of the second kind.
