Subsequently, they suggested that element 104 be named kurchatovium (symbol Ku) to honor Igor Kurchatov, a Soviet pioneer in nuclear physics.
In 1969, an American research team led by A. Ghiorso at the Lawrence Berkeley National Laboratory announced that, while they had been unable to confirm the Dubna group's results, they had identified at least two isotopes of element 104 different from the one identified by the Soviet scientists.

The UC group also stated that they could not reproduce the earlier synthesis by Soviet scientists.
This resulted in an element naming controversy; Since the Soviets claimed that it was first detected in Dubna, Dubium (Db) was suggested, as was Kurchatovium and symbol Ku for element 104, in honor of Igor Vasilevich Kurchatov[?] (1903-1960), former Head of Soviet Nuclear Research.
The Americans, however, proposed Rutherfordium (symbol Rf) for the new element to honor Ernest R. Rutherford a noted New Zealand nuclear physicist.

Russsian investigators who claim to have first discovered element 104, isotope 260 (half-life 0.3 seconds) in 1964 at Dubna proposed the name kurchatovium.

New data, reportedly issued by Soviet scientists, hve reduced the half-life of the isotope they worked with from 0.3 to 0.15 s.
The Dubna scientists suggest the name kurchatovium and symbol Ku for Element 104, in honor of Igor Vasilevich Kurchatov (1903-1960), late Head of Soviet Nuclear Research.
In 1969 Ghiorso, Nurmia, Harris, K.A.Y. Eskola, and P.L. Eskola of the University of California at Berkeley reported that they had positively identified two, and possibly three isotopes of Element 104.

History: The first claim for element #104 came in 1964 from a group of scientists headed by Georgy Flerov at the JINR in Dubna, USSR, who had bombarded plutonium-244 with neon-22 ions.
They named the element kurchatovium (Ku) after Igor Kurchatov, the head of the Russian nuclear research program.
The claim was disputed in 1969 by a group of scientists led by Albert Ghiorso at Berkely, California.

It alluded to the fact that the element, which has the atomic number 104, was first reported by Georgii Flerov and colleagues at the Joint Institute for Nuclear Research in Dubna, Russia, in 1964.
The Russian scientists named the element “kurchatovium” in honor of nuclear physicist Igor Kurchatov (1903–60), who was a driving force behind the Soviet Union’s race to develop the atomic bomb.
For the next 10 years or so, the Dubna group published numerous papers on the element, including papers in 1969 and 1970 that provided evidence of the production of the isotope rutherfordium-259.

Nuclear chemistry knows many methods of producing these elements.
At present, 12 transuranium elements are known, namely: neptunium, plutonium, americium, curium, berkelium, californium, einsteinium, fermium, mendelevium, lawrencium, and kurchatovium, the latter being the heaviest transuranium element synthesized just recently (in 1964) by a group of Soviet physicists headed by P. Flerov.
One of the transuranium elements, that having the atomic number 102, has not yet been named.
