Joint Institute of Nuclear Research

In October 2006, a research team of scientists from the Lawrence Livermore National Laboratory in California, USA, and the Joint Institute of Nuclear Research in Dubna, Russia, reported the indirect detection of Uuo-294 (Element 118). It is reported to be produced by the following collisions. 

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 December 1998 the Lawrence Berkeley Laboratory sent a supply of plutonium-244 and calcium-48 to Russian scientists at the Joint Institute of Nuclear Research in Dubna, Russia. The Russians bombarded the plutonium with ions of calcium, which, after some time, produced a single atom of ununquadium-289. Uuq has a half-life of just 30 seconds, after which it decays successively into element 112 (ununbium), element 110, (darmstadtium), and element 108 (hassium). The Russian nuclear laboratory later synthesized several atoms of other isotopes of Ununquadium. 

A joint Russian and American team of physicists created two new super heavy elements—115 and 113—that provide more support for the island of stability concept. The experiments were conducted between July 14 and August 10 in 2003, but the results of the experiments were not published until February 2004. The experiments were conducted in the Joint Institute of Nuclear Research (JINR) in Dubna, Russia, and also involved the scientists of the Lawrence Berkely National Laboratory located at Berkeley, California. Only four atoms of two isotopes of ununpentium (element 115) were produced, and the results were published in a peer-reviewed scientific journal. Following is the nuclear reaction that produced these four atoms ...

This kind of experiment is easy to describe but very difficult to carry out. In fact, this research is carried out at only several laboratories in the world. One is the Joint Institute of Nuclear Research, in Dubna, Russia. The second is the Lawrence Berkeley Laboratory at the University of California at Berkeley in the United States. The third is the Institute for Heavy Ion Research in Darmstadt, Germany. All of these laboratories use large particle accelerators that cost millions of dollars. Dozens of scientists from many different countries work on each team.

Dubnium — (named after the Joint Institute of Nuclear Research in Dubna, Russia). Db at. wt. [262] at. no. 105. In 1967 G. N. Flerov reported that a Soviet team working at the Joint Institute for Nuclear Research at Dubna may have produced a few atoms of "105 and " 105 by bombarding Am with Ne. Their evidence was based on time-coincidence measurements of alpha energies. More recently, it was reported that early in 1970 Dubna scientists synthesized Element 105 and that by the end of April 1970 had investigated all the types of decay of the new element and had determined its chemical properties. In late April 1970, it was announced that Ghiorso, Nurmia, Harris, K. A. Y. Eskola, and P. L. Eskola, working at the University of California at Berkeley, had positively identi-...
