Subject: Russia-Livermore Scientists may have produced elusive
heavy element 114

A Russian-Livermore experiment at Russia's Joint Institute for
Nuclear Research in Dubna my have produced the long-sought
element 114, according to news reports out of Russia.

The Dubna accelerator fired calcium-48 atoms into a Livermore
supplied target of Plutonium-244 in a 40 day experiment that
wrapped up at the end of December 1998. Detectors picked up
signs of a single atom of a heavy element, tentatively
identified as 114, by a tell-tale sequence of alpha-particle
emissions followed by a spontaneous fission, due to decay of the
atom and the subsequent decay of it's daughters".

Livermore nuclear chemist Ken Moody spoke with caution about the
experiments. "these are very interesting findings," he said.
"The analysis we are doing now should tell us how to interpret
the results."

"If confirmed, the synthesis of element 114 will create an
important new opportunity to study the physics of extrememly
heavy elements," said Energy secretary Bill Richardson.
"creating 114 has long been a goal of Nuclear Physicists. It is
significant that this latest experiment is an international
effort, a collaborative project involving Russian scientists at
Dubna, and American scientists from DOE's Lawrence Livermore
National Lab".

Livermore's participation was supported by Laboratory Directed
Research and Development. Moody and collaborators Ron Lougheed,
John Wild, Nancy Stoyer and Mark Stoyer of the Analytical and
Nuclear Chemistry division supplied the plutonium target and
participated in the design and implementation of the
experiments, and the subsequent data analysis. They have worked
in the highly competitive field of heavy element sysnthesis at
the three world's major centers for such research, in Berkeley,
Dubna and Darmstadt, and are careful not to count chickens
prematurely.

Still, they agree it is an exciting time. Synthesizing element
114 is a long sought goal because of theoretical predictions
that it will be part of an "island of stability" in an ocean of
instability. Lighter (but still extremely heavy) elements like
108 last only thousandths of a second before falling apart. The
observations at Dubna suggested a 30-second lifetime for the 114
candidate, a veritable Rock of Gibraltar compared to some of its
more ephemeral neighbors.
