Db respectively. However, later evidence gave a much lower SF branching for 261 Bh reducing confidence in this assignment. The assignment of the dubnium activity was later changed to 258 Db, presuming that the decay of bohrium was missed. The 2 ms SF activity was assigned to 258 Rf resulting from the 33% EC (electron capture) branch. 15.78 His results in international tournaments include 2nd at Polanica-Zdrój 1970; 2nd at Dubna 1976; 1st at Quito 1976. First steps North Korea's nuclear program began under Kim il-Sung in the mid-1950s, when North Korean scientists started practical training courses at the Joint Institute for Nuclear Research in Dubna in the Soviet Union. There, they studied electronic physics radiochemistry, high-energy physics and other subjects. These efforts were initially focused on the peaceful use of atomic energy; Soviet-North Korean agreements of the time specifically emphasized the peaceful nature of bilateral cooperation in the nuclear sphere. An intergovermental agreement on cooperation in the field of atomic energy, signed in 1959, laid the foundation for joint nuclear activities between the Soviet Union and North Korea. On the basis of this agreement, the two countries signed the so-called "Series 9559" contracts, concerning matters such as the conduct of geological studies, the construction of a nuclear research center (called a "Furniture Factory" by the North Koreans), and the training of North Korean labor. ''The North Korean Nuclear Program'' Other North Korean scientists received their education in East Germany and China (People's Republic of China). In 1961, North Korea launched a major nuclear development program at Yongbyon, some 60 miles north of Pyongyang. In 1965, the Soviet Union provided North Korea with a 2 MW IRT-2000 research reactor for the Yongbyon nuclear facility, and supplied fuel over the years of the reactor's operation. Oleg V. Davidov, “Russia’s Position towards North Korea’s Nuclear Development" thumb Theoretical electron structure of ununoctium. Very little about this element is yet known.

The elusive element was first detected in 1998 at the Joint Institute for Nuclear Research (w:Joint Institute for Nuclear Research), Dubna (w:Dubna), Russia, when a plutonium target was bombarded with calcium ions accelerated in a cyclotron (w:cyclotron). Until now no other groups had been able to confirm the Russian team's results. "It’s unusual for important results like the Dubna group’s claim to have produced 114 to go unconfirmed for so long," said Ken Gregorich, part of the Berkeley team.

As of February 2010, only the elements up to 112, copernicium, have been confirmed as discovered by IUPAC, while claims have been made for synthesis of elements Ununtrium 113

for it. The name and symbol were officially endorsed by IUPAC on February 19, 2010.
