UNILAC accelerator

Hassium — (named for the German state, Hesse) Hs at. wt. [277] at. no. 108. This element was first synthesized and identified in 1964 by the same G.S.I. Darmstadt Group who first identified Bohrium and Meitnerium. Presumably this element has chemical properties similar to osmium. Isotope 108 was produced using a beam of Fe projectiles, produced by the Universal Linear Accelerator (UNILAC) to bombard a Pb target. Discovery oiBohrium Bind Meitnerium was made using detection of isotopes with odd proton and neutron numbers. 

We introduced the nuclide symbols used here in Section 2.3. The equation is a sununary of the following. A highspeed zinc-70 nucleus (as an ion, which is an electrically charged atom) smashes into a lead-208 target where, as the arrow denotes, it yields new products, a nucleus of element 112 (mass number 277) and a neutron, denoted qH. Element 112 has the provisional name of ununbium until several other laboratories can reproduce the work, after which the discoverer may name it. Figure 2.16 shows the ion accelerator (UNILAC) that produced the zinc ions for this experiment.
