There are better pages too :-)

<< The researchers expose the clear canister of liquid to pulses of neutrons
every five milliseconds, or thousandths of a second, causing tiny cavities
to form. At the same time, the liquid is bombarded with a specific frequency
of ultrasound, which causes the cavities to form into bubbles that are about
60 nanometers - or billionths of a meter - in diameter. The bubbles then
expand to a much larger size, about 6,000 microns, or millionths of a
meter - large enough to be seen with the unaided eye.
"The process is analogous to stretching a slingshot from Earth to the
nearest star, our sun, thereby building up a huge amount of energy when
released," Taleyarkhan said.
Within nanoseconds these large bubbles contract with tremendous force,
returning to roughly their original size, and release flashes of light in a
well-known phenomenon known as sonoluminescence. Because the bubbles grow to
such a relatively large size before they implode, their contraction causes
extreme temperatures and pressures comparable to those found in the
interiors of stars. Researches estimate that temperatures inside the
imploding bubbles reach 10 million degrees Celsius and pressures comparable
to 1,000 million earth atmospheres at sea level.
At that point, deuterium atoms fuse together, the same way hydrogen atoms
fuse in stars, releasing neutrons and energy in the process. The process
also releases a type of radiation called gamma rays and a radioactive
material called tritium, all of which have been recorded and measured by the
team. In future versions of the experiment, the tritium produced might then
be used as a fuel to drive energy-producing reactions in which it fuses with
deuterium. >>

Wondering whether there is an anti-bubble sonofusion effect,
or an anti-bubble/bubble sonofusion effect, but do not take
it too seriously!
