VORTEX ARRAYS OF COEXISTING SINGLY AND DOUBLY QUANTIZED VORTEX LINES IN HE-3-A

In superfluid He-3-A singly and doubly quantized vortex lines call coe xist in a rotating container. We measure with NMR techniques tile radi al distribution of the two vortex types in an array of vortex lines. T he radial composition is found to depend on tile procedure by which th e array has been formed. The result shows that in superfluid He-3 the energy barriers separating different configurations of the vortex arra y are inpenetrably high for a metastable state to relax.
