Abstract
Measurements of light scattered off a bubble that is illuminated by a train of short pulses enables one to resolve the strongly supersonic c ollapse of a sonoluminescing bubble. We find that the collapse is fast er than Mach 4 (relative to the ambient speed of sound of the gas in t he bubble) and that the flash of sonoluminescence is emitted within 50 0 ps of the minimum bubble radius, at about which time the bubble's ac celeration is greater than 10(11) g.
