Heavy ion linear accelerator

In 1967 the scientists of the Joint Institute of Nuclear Research in Dubna, Russia, bombarded americium-243 with neon-22 to produce two isotopes of unnilpentium, then known as hahnium. The reaction is as follows jAm-243 + Ne-22 —> jjjjHahnium-260 and 261 (Unp-260 and 261). In 1970 Albert Ghiorso and his team at Berkeley bombarded califor-nium-249 with heavy nitrogen (N-15) in their Heavy Ion Linear Accelerator (HILAC). The reaction is as follows gCf-249 + -15 —> j jHa-260 (Unp-260). 

In October 1971. Ghiorso and co-workers at Berkeley, using the heavy ion linear accelerator, announced production of element M 105 by bombarding 25llCf with, 5N and by bombarding 4,Bk with " O. The isotope emits 8.93-MeV alpha particles, decaying to 2,7l.r with a half-life of about... 

The bombardment was effected in the new Hilac, or heavy ion linear accelerator, in Berkeley. A linear accelerator, as the name implies, accelerates particles along a straightaway rather than around a circular course as in the cyclotron or bevatron. 

Heavy Ion Linear Accelerator (Super HILAC) as a source of heavy ions to bombard a 259- ig target of This resulted in the production and positive identification of 106, which decayed with a half-life of 0.9 0.2 s by the emission of alpha particles as follows ...
