Description |
|
| The discovery of Element 106 took place in 1974 almost simultaneously at the Lawrence-Berkeley Laboratory and at the Joint Institute for Nuclear Research at Dubna (near Moscow). The Berkeley Group, under direction of Ghiorso, used the Super-Heavy Ion Linear Accelerator (Super HILAC) as a source of heavy oxygen-18O ions to bombard a 259 microgram target of californium-249. This resulted in the production and positive identification of Element 106-263, which decayed with a half-life of 0.9 ± 0.2 s by the emission of alpha particles. The Dubna Team, directed by Flerov and Organessian, produced heavy ions of chromium-54 with their 310-cm heavy-ion cyclotron to bombard lead-207 and lead-208 and found a product that decayed with a half-life of 7 ms. They assigned Element 106-259 to this isotope. It is now thought six isotopes of Element 106 have been identified. Two of the isotopes are believed to have half-lives of about 30 s. In 1997, IUPAC adopted the name seaborgium for Element 106. 1 |
