Excerpt: Meitnerium - Wikipedia, the free encyclopedia Meitnerium was first synthesized on August 29, 1982 by a German research team led by Peter Armbruster and Gottfried Mnzenberg at the Institute for Heavy Ion Research (Gesellschaft fr Schwerionenforschung) in Darmstadt. The team bombarded a target of bismuth-209 with accelerated nuclei of iron-58 and detected a single atom of the isotope meitnerium-266: Bi + Fe Mt + Element 109 was formerly known as Unnilennium, bearing the symbol Une. Historically, element 109 has been referred to as eka-iridium. The name meitnerium (Mt) was suggested in honor of the Austrian physicist Lise Meitner. In 1997, the name was officially adopted by the IUPAC. The team at RIKEN, Japan, have indicated that as part of their ongoing studies using Cm targets, they may study the new reaction Cm(Al,xn) in the future. The below table contains various combinations of targets and projectiles which could be used to form compound nuclei with Z=109. This section deals with the synthesis of nuclei of meitnerium by so-called "cold" fusion reactions. These are processes which create compound nuclei at low excitation energy ( 10-20 MeV, hence "cold"), leading to a higher probability of survival from fission. The excited nucleus then decays to the ground state via the emission of one or two neutrons only. The first success in this reaction was in 1982 by the GSI team in their discovery experiment with the identification of a single atom of Mt in the 1n neutron evapora...
