Abstract

We have observed and characterized the dynamics of singly quantized vortices in dilute-gas Bose- Einstein condensates. Our condensates are produced in a superposition of two internal states of 85Rb, with one state supporting a vortex and the other filling the vortex corc. Subsequently, the state filling the core can be partially or completely removed, reducing the radius of the core by as much as a [actor of 13. all the way down to its bare value of the healing length. The corresponding superfluid rotation rates, evaluated at the core radius, vary by a factor of 150, but the prccession fl-eqtiency of the vortex core about the condensate axis changes by only a factor of 2.
