Element (108)

Element 108, chemical element; for physical constants see Periodic Table. Peter J. Armbruster and his co-workers in West Germany at the Heavy Ion Research Laboratory (GSI) at Darmstadt produced element 108 with mass number 265 by bombarding lead-208 with iron-58 nuclei. The recoiling product atom was separated by a newly developed velocity filter. The new element decayed by three consecutive alpha-particle emissions to element 106 in 2.4 ms and then to element 104 in 360 ms, and finally to nobelium in9.8 seconds.
