Historia
Scientists working at the Joint Institute for Nuclear Research in Dubna, USSR reported their discovery of element 106 in June 1974.
Synthesis was also reported in September 1974 at the Lawrence Berkeley Laboratory by the workers of the Lawrence Berkeley and Livermore Laboratories led by Albert Ghiorso and E. Kenneth Hulet.
It was produced by collisions of californium-249 with oxygen atoms.
