Abstract

A mechanism that, when combined with recent single-bubble sonoluminescence (SBSL) models, predicts temperatures high enough for light emission is proposed. Because of the vanishing free volume as the bubble approaches maximum compression, the particle-producing dissociation reactions are shown to be suppressed by Le Chatelier's principle for the excluded volume gas, to a degree far beyond what could be expected in an ideal gas.
