N2 - The first measurements of vortex diffusivity in two-dimensional superfluid helium films are reported. The diffusivity appears to be a universal function of sT, where s is the areal superfluid density, and is 0.4m at the Kosterlitz-Thouless transition. In contrast with theoretical expectations, the diffusivity is a rapidly increasing function of Ts near the transition temperature.
