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