Abstract
The free energy of rotating /sup 3/He-A in zero magnetic field and large cylinders (R >> 10 ..mu..m) is calculated for several textural configurations at slow rotation speeds (..cap omega.. approx. = h/2mR/sup 2/). The sequence of equilibrium states with increasing ..cap omega.. is studied near T/sub c/. A transition from the Mermin-Ho state to one of higher circulation should occur for ..cap omega.. approx. = 9.6 h/2mR/sup 2/. This transition may be delayed, however, by the onset of azimuthal distortion (''swirl'') in the Mermin-Ho state. A new experimental method is proposed for studying various textural configurations, based on the anisotropy of negative-ion mobility. Significant and characteristic focusing should occur when ions are swept through long cylinders of length L > 10R. In addition, time-of-flight information can also help identify the textural state. Finally, the qualitative effects of weak magnetic fields and lower temperatures are discussed.
