Abstract

Recent theoretical work in single bubble sonoluminescence has suggested that water vapor in the collapsing bubble leads to energyconsuming chemical reactions, restricting the peak temperatures to values for which hardly any light emission would occur. We demonstrate in an ab initio statistical approach that the excluded volume of the non-ideal gas results in a pronounced increase of the equilibrium constant and a respective suppresion of the (endothermic) particle producing reactions. Thus, sufficiently high temperatures for considerable bremsstrahlung emission can be achieved
