Abstract

T-P phase diagram of oxygen with the liquid and solid phases (alpha, alpha,(alpha) over tilde, beta, gamma and is an element of) is calculated using the mean field theory. By expanding the free energy in terms of the order parameter, the phase line equations are derived and they are fitted to the experimental T-P data from the literature.
