Extensive experimental mapping of sonoluminescence parameter space

Experimental phase diagrams are compared to theoretical predictions based o n the Dissociation Hypothesis (DH) theory of single bubble sonoluminescence (SBSL). Ambient radius (R-0)- acoustic drive pressure (P-a) phase diagrams are presented for krypton-nitrogen mixtures and for a collection of data w ith other noble gas-nitrogen mixtures. The data is also presented in terms of expansion ratio (maximum bubble radius R-max/ R-0) vs P-a and relative l ight intensity vs P-a. The results provide further evidence of thr validity of DH and also provide a thorough mapping of SBSL at a single frequency.
