title: Detection of excited-state electron bubbles in superfluid helium.
abstract: We report on experiments in which the pressure oscillation associated with a sound wave is used to explode electron bubbles in liquid helium. Using this technique, we are able to detect the presence of electron bubbles in excited states.
