Novel methods to create multielectron bubbles in superfluid helium.
An equilibrium multielectron bubble (MEB) in liquid helium is a fascinating object with a spherical two-dimensional electron gas on its surface. We discuss two ways in which they have been created. For MEBs that have been observed in the dome of a cylindrical cell with an unexpectedly short lifetime, we show analytically why these MEBs can discharge by tunneling. Using a novel method, MEBs have...
متن کاملFission of Multielectron Bubbles in Liquid Helium
The stability of multielectron bubbles (MEBs) in liquid helium is investigated using the liquid-drop model for fissioning nuclei. Whereas a critical positive pressure can make the bubble unstable against fissioning, a small negative pressure suffices to introduce a restoring force preventing any small deformation of the bubble to grow. We also find that there exists an energy barrier making MEB...
متن کاملProperties of multielectron bubbles in liquid helium
of a bubble (F is the diele~tric onstant of liquid helium) gives the class~cal *'Coulomb radius" of the bubble (this value is accurate for the bubbles considered ( 5 , 6)). For typical charges Z of 10510' electrons, this yields radii between 10 and 100 pm. The electrons in a bubble are confined to a narrow region of only a fcw Bngstrorns width close to the bubble surface, owing to their mutual ...
متن کاملUnexpected Hydrodynamic Behavior of Multielectron Bubbles in Liquid Helium I
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 fac...
متن کاملStabilization of Multi-electron Bubbles in Superfluid Helium
Multielectron bubbles (MEBs) in liquid helium were first observed in the late 1970s, but their properties have never been explored experimentally due to their short lifetimes and the difficulty to localize them. We report the observation of longlived MEBs in a novel cell filled with superfluid helium at static negative pressures. MEBs were extracted from the electron filled vapor sheath of a he...
