In cavitation experiments with deuterated acetone,
tritium decay activity above background levels was detected. In
addition, evidence for neutron emission near 2.5 million electron volts was also observed, as would be expected for deuterium-deuterium fusion.
Control experiments with normal acetone did not result in tritium
activity or neutron emissions. Hydrodynamic shock code simulations
supported the observed data and indicated highly compressed, hot
(106 to 107 kelvin) bubble implosion
conditions, as required for nuclear fusion reactions.
