Abstract
The motion of ions along vortex lines in the presence of a transverse radio-frequency electric field has been investigated. An anomaly in the velocity-versus-electric-field relation, associated with the "resonant" generation of vortex waves, is observed. These measurements constitute the first observation of vortex waves at frequencies larger than a few hertz.Keywords
