Abstract : The discovery of single-bubble sonoluminescence has led to a number of interesting discoveries and provocative claims-among these are that hydrogen isotope fusion could be accomplished with a collapsing cavitation bubble and that the sonoluminescence emissions are first demonstration of quantum vacuum radiation. This project has sought to understand the nonlinear bubble dynamics associated with the phenomenon, and has specifically involved the conditions necessary for bubble levitation and sonoluminescence extinction.
