INTERACTION OF INJECTED CHARGES WITH QUANTUM VORTICES IN SUPERFLUID HELIUM NEAR THE SURFACE
The motion of injected negative charges under free liquid surface, as well as in superfluid He-II volume at temperatures T ≈ 1.5 K in static electric fields of different configuration has been experimentally investigated. It is found, that in case of electric field configuration, which presses the charges to the He-II free surface there is a noticeable deviation of current density distribution from given by electric field, and in case of configuration when the charges move in the He-II volume, current density coincides with the electric field force lines.
