Abstract:
Previous measurements have demonstrated that a small noble gas concentration is essential to the attainment of stable bright sonoluminescence from bubbles formed in a water nitrogen mixture. As the chemical properties of nitrogen and oxygen are quite different, these experiments for mixtures of water and oxygen have been repeated. Again, it is found that noble gas doping is an important aspect of the physics, and that there is a strong similarity between the behavior of the nitrogen and oxygen systems.
