Electron bubbles in helium clusters. II. Probing superfluidity

The Journal of Chemical Physics, 2006
In this paper we present calculations of electron tunneling times from the ground electronic state of excess electron bubbles in (He4)N clusters (N=6500–107, cluster radius R=41.5–478Å), where the equilibrium bubble radius varies in the range Rb=13.5–17.0Å.

Roton-pair creation by electron bubbles in helium

Physical Review B, 1995
Electrons in superfluid helium form cavities that displace hundreds of atoms. These ``electron bubbles'' characteristically emit rotons in pairs when accelerated by an electric field. As no symmetry prevents the emission of single rotons, this has long been a mystery.

2D Electron Bubbles in Gaseous Helium

Journal of Low Temperature Physics, 2005
The structure of 2D electron bubbles in gaseous helium is discussed. These cavities appear under the condition ng > nc, where nc ≈ 1020 cm−3 is much less than the critical helium gas density for the appearance of 3D electron bubbles. Far from the critical density, the 2D bubble trapping energy is practically a linear function of ng. Experiment confirms
