ORIENTATIONAL ORDER IN FCC SOLID ORTHO-H2. GREEN FUNCTION TREATMENT OF THE INTERNAL FIELD APPROXIMATION.

Abstract

The technique of temperature-dependent Green functions is applied to a molecular field model of the orientational order-disorder transition of ortho-H2 molecules on an fcc lattice. The chain of equations for the various Green functions is decoupled by an approximation similar to the one used by Tahir-Kheli and ter Haar, which enables one to solve the three remaining Green function equations of motion. It is shown that the Green function approach leads to the same results as the more conventional methods. (Author)
