Properties of Few-Electron Bubbles in Superfluid Helium-4

We present calculations of the properties of bubbles in liquid helium-4 containing 3 or 8 electrons. The pressure range in which these bubbles are stable is determined. For Z =3, we find that the bubbles are unstable except in a pressure … Continue reading
