In January, 2001 the Joint Institute for Nuclear Research, Dubna,
published results  that described the decay of the isotope
Uuh, which was produced in the reaction of
Cm with 48
Ca. It has a half-life of about
0.6 milliseconds (0.0006 seconds) and decayed into 288Uuq
On May 11th, 2001, the institute reported synthesizing a second
atom, and that the properties confirmed a region of "enhanced"
stability. Confirmation of these results is still pending.
1999, researchers at Lawrence Berkeley National Laboratory
announced the discovery of elements 116 and 118, in a paper
published in Physical Review Letters. The following
year, they published a retraction after other researchers were
unable to duplicate the results. In June 2002, the director of
the lab announced that the original claim of the discovery of
these two elements had been based on data fabricated by the
principal author Victor Ninov.
