Where is Seaborgium Found?
In September 1974, workers of the Lawrence Berkeley and Livermore Laboratories also claimed creation Element 106 “without any scientific doubt.” The LBL and LLL Group used the Super HILAC to accelerate 18O ions onto a 249Cf target.
Element 106 was created by the reaction 249Cf(18O, 4N)263X, which decayed by alpha emission to rutherfordium, and then by alpha emission to nobelium, which in turn further decayed by alpha between daughter and granddaughter. The element so identified had alpha energies of 9.06 and 9.25 MeV with a half-life of 0.9 +/- 0.2 s.
