N2 - We report spectacular features on the velocity-force characteristics of a vibrating wire resonator in superfluid He-3-B at ultralow temperatures. We see steps and discontinuities in the characteristics. The steps display two separate critical velocities where firstly some 'event' occurs, causing the wire to lose energy and lose amplitude, followed by a second lower critical velocity where the 'event' decouples. We speculate that these events arise from vortex loop creation at asperities on the vibrating wire.
