A Green's function approach is used to derive an approximate expression for the grand potential in the presence of a magnetic field. This approximation is used to derive a relation between the A/sub 1/, A, and B phases as functions of temperature and magnetic field strength. Where the approximation is quantitatively valid, comparison with experiment is made, as a result of which a value for the gap rather less than the BCS value is derived. A value for the difference between the Balian--Werthamer and Anderson--Brinkman-Morel terms in the grand potential to sixth order in the gap function at the polycritical pressure is also found.
