title: Ambient acceleration dependence of single-bubble sonoluminescence.
abstract: Much of the research performed to study SBSL deals with the influence of external parameters (e.g., the host water temperature, the ambient pressure, the type and amount of dissolved gas in the liquid, to name a few) on the bubble dynamics and light emission. In the current paper, work carried out to study the influence of another external parameter-ambient acceleration-is described. The experiments described here were performed on the NASA KC-135 which provided both periods of reduced gravity (10(-3) g) and increased gravity (1.8 g) by flying repeated parabolic maneuvers. The resulting measurements are compared with the predictions of a numerical model and can be understood in the context of the changing hydrostatic head pressure and buoyant force acting on the bubble.
