aking into account variation of heat conductivity of a noble gas up
to 2500 oK, we have investigate effect of thermal conduction on
sonoluminescence radiation. Results of our numerical simulation show
that thermal conductivity plays an important role in the bubble
evolution at the collapse with a remarkable effect on the bubble
peak temperature and its chemical activity. Calculated intensity of
light emission by thermal-bremsstrahlung mechanism shows that at
fixed degassing conditions, light intensity increases with driving
pressure as well as with noble gas atomic mass, which is in a close
agreement with available experimental reports.
