  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 reach. A sequence of two and higher order photon correlation
experiments is outlined.
