The interaction between injected negative charges and vortex motion formed by standing waves with the frequency ω/2π = 49.88 Hz on the surface of normal and superfluid helium has been experimentally studied. It has been found that the vorticity generation results in the redistribution of the current at segments of a collector. A change in the trajectory of the motion of charges from a source to a receiving collector is caused by their interaction with the vortex flow of the normal component.
Key words: superfluid helium, vortex motion, injected charges.
