Abstract: We use optical images of a superfluid consisting of a weakly interacting Bose–Einstein condensate
of sodium atoms to investigate the structure of quantized three-dimensional vortex filaments. We find that
the measured optical contrast and the width of the vortex core quantitatively agree with the predictions of the
Gross–Pitaevskii equation.
