The interaction between injected charges and a vortex flow in normal and superfluid helium near ТλI. A. Remizov1,2, M. R. Sultanova1,2, A. A. Levchenko1,2, and L. P. Mezhov-Deglin1,2 1Institute of Solid State Physics, Russian Academy of Sciences, Chernogolovka 142432, Russia 2Landau Institute for Theoretical Physics, Russian Academy of Sciences, Chernogolovka 142432, Russia Received January 18, 2021 , published online March 26, 2021 Abstract 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.
