The authors report weak-coupling numerical calculations of the order parameter and the free energy of isolated vortices in superfluid {sup 3}He in the framework of the quasiclassical theory of superfluid Fermi-liquids. Unlike earlier work with the Ginzburg-Landau theory, these results are not restricted to the vicinity of {Tc}. The authors show that Fermi-liquid effects play an important role at lower temperatures. It appears there is a transition from the double core vortex to an A-phase-core vortex at the vapor pressure just above 0.5{Tc}.
