Element (106)

workers mass research

Element 106, chemical element; for physical constants see Periodic Table. In June 1974, workers at the Joint Institute for Nuclear Research at Dubna (USSR) reported producing element 106 by bombarding lead-206, 207, and 208 with chromium-54. In Sept. 1974, Albert Ghiorso and co-workers bombarded californium-249 with oxygen-18 to produce element 106 with mass number 263. In 1984, Peter J. Armbruster and his co-workers in West Germany at the Heavy Ion Research Laboratory (GSI) at Darmstadt produced element 106 with mass number 261. It was seen to be a decay product of element 108 at this time.
