✦ Synopsis

We have investig4ated multielectron bubbles (with charges Z,,, 10 6 electrons) in normal liquid He. The drift velocity in an electric field and the charge of the bubbles were measured simultaneously. We found the drag coeJficient to be over an order of magnitude higher than expected from ordinary hydrodynamics. The velocities did not show a correlation with the charge and could vary up to a factor of 3 for equally charged bubbles.
