Abstract

Deviations from isotropic emission in sonoluminescence (SL) have been resolved to about one part per thousand. States with larger dipole components are characterized by large fluctuations in the intensity of SL. When dipole components exceed the threshold of detectability their magnitude decays on a long time scale. This data can be interpreted as monitoring the degree of nonsphericity of the bubble collapse that leads to SL.
