SONOLUMINESCENCE IN HIGH MAGNETIC-FIELDS

We have made a detailed study of sonoluminescence (SL) in high magneti c fields. In magnetic field sweeps at constant levels of acoustic driv e, SL disappears above a pressure-dependent threshold magnetic held. S weeps of acoustic drive at fixed magnetic fields show that the upper a nd lower bounds of forcing pressure that determine the region of SL in crease dramatically with magnetic field. This interplay between acoust ic and magnetic fields suggests that the primary effect of magnetic fi elds on SL is to alter the condition for stable hubble oscillations.
