(color online) (a) Spectrum of A-phase of superfluid ³He with the energy gap closed at two nodes p_± and maximized at the equator. There are preferential orientations for the spontaneous orbital angular momentum l and the spin anisotropy d ^ . (b) Spectrum of the B-phase with an isotropic energy gap. The spin anisotropy orientation d ^ is locked to that of the angular momentum, but there is no preferential orientation for the composite.
