Abstract
The blackbody spectra, and similar sonoluminescence intensities of He and Xe bubbles suggest that the interior of a sonoluminescing bubble is highly stressed and dense. Molecular dynamic simulations indicate interior temperatures which are enhanced by thermal conduction and can approach 1 MK. Furthermore the gas passes through states where the mean free path is larger than the distance over which temperature varies and so calls into question the value of theories based on hydrodynamics. To search for rare fusion events a neutron detector with 25% total discriminated quantum efficiency has been built. It can time stamp neutron arrival and sonoluminescence to better than 1 ns and record tracks on the fly. [Work supported by DARPA.]
