Sonoluminescence may be studied in detail by intensity correlations among the emitted photons. As an example, we discuss an experiment to measure the size of the light-emitting region by the Hanbury Brown-Twiss effect. We show that single bubble sonoluminescence is almost ideally suited for study by this method and that plausible values for the physical parameters are within easy experimental r...

The evolution of the cavitation noise (CN) spectra in field a focusing emitter with an increase intensity ultrasound (US) was studied. Spectra without subharmonics f 0 /2 were recorded for first time, where is frequency generating cavitation,. Such spectrum observed partially degassed water at high duty cycle ultrasonic pulses. threshold appearance sonoluminescence (SL) coincides CR spectrum. I...

Time spectra of neutron and sonoluminescence emissions were measured in cavitation experiments with chilled deuterated acetone. Statistically significant neutron and gamma ray emissions were measured with a calibrated liquid-scintillation detector, and sonoluminescence emissions were measured with a photomultiplier tube. The neutron and sonoluminescence emissions were found to be time correlate...

Sonoluminescence is the intriguing phenomenon of strong light flashes from tiny bubbles in a liquid [1]. These bubbles are driven by an ultrasonic wave and need to be filled with noble gas atoms. The spectrum of the emitted light corresponds to very high temperatures [2] and hints the presence of an hot opaque plasma core [3]. Although sonoluminescence has been studied extensively, the origin o...

We draw attention to the fact that the popular but unproven hypothesis of shock-driven sonoluminescence is incompatible with the reported synchronicity of the single bubble sonoluminescence (SBSL) phenomenon. Moreover, it is not a necessary requirement, since we show that the sub-shock dynamic heating in gas bubble cavitation can lead to conditions required to generate intense 100ps light pulse...
