We present a review of the properties of negative ions that are produced when electrons are inserted into superfluid helium-4. It is convenient to divide the ions into two groups. The first is the ion usually referred to as the “normal electron bub

In 1970, Doake and Gribbon reported the discovery of a negative ion in superfluid helium that has a mobility about six times higher than the mobility of the normal electron bubble. We report on measurements of the variation of the mobility of this

A freshman mechanics course often includes a theoretical discussion or demonstration of the motion of solid particles through fluids. The effect of viscosity is typically considered to provide a drag force on the particle which at each instant is pro

Multielectron bubbles (MEBs) are charged cavities in liquid helium which provide an interesting platform for the study of electrons on curved surfaces. Very recently, we have reported an experiment to trap these objects in a two-dimensional Paul trap

An electron bubble in liquid helium-4 under the saturated vapor pressure becomes unstable and explodes if the pressure becomes more negative than −1.9 bars. In this paper, we use focused ultrasound to explode electron bubbles. We then image at 30,0

We present the results of computer simulations of the motion of an electron bubble through superfluid helium-4 when acted upon by an electric field. The simulations are based on an extended version of the Gross–Pitaevskii equation. The temperature

Exotic ions are negatively charged objects which have been detected in superfluid helium-4 at temperatures in the vicinity of 1 K. Mobility experiments in several different labs have revealed the existence of at least 18 such objects. These ions have
