Abstract
We describe the observation of new dynamical effects in multibubble sonoluminescence (MBSL). The experiments show a specific time-dependent nonmonotonic response of MBSL in aqueous solutions to hydrodynamical perturbations caused by sudden pressure changes. Such response as well as observations of the asymmetrical and nonmonotonic changes in the intensity and width of the sodium emission with hydrodynamic perturbations have been interpreted as the manifestations of the cooperative dynamical phase transition effect.Keywords
