Abstract
We report transverse and longitudinal NMR experiments on superfluid - confined within 2-μm-diam tubes at temperatures down to 1 mK. The behavior of the transverse resonance line provides evidence for a slow transition between two textures in the tubes; the shifts are smaller than in bulk for both textures. A search for longitudinal resonance was unsuccessful, and no transition to the phase was observed.
