Subsequent research in the following decade (primarily at Berkeley and Dubna) led the International Union of Pure and Applied Chemistry to conclude that Dubna papers published in 1966 established the existence of the isotope nobelium-254 with an alpha-decay half-life of about 51 seconds. Kurchatov Institute of Atomic Energy, Moscow, and at Dubna) and in the United States (Berkeley) failed to confirm the Stockholm discovery. Other experiments performed in the Soviet Union (at the I.V. In the same year, a Soviet scientific team led by Georgy Flerov at the Joint Institute for Nuclear Research in Dubna, Russia, achieved a similar result. Seaborg at the University of California, Berkeley, reported the isotope 254 as a product of the bombardment of curium (atomic number 96) with carbon ions (atomic number 6) in a heavy-ion linear accelerator. In 1958 American chemists Albert Ghiorso, T. They reported synthesis of an isotope of element 102 (either isotope 253 or 255) that decayed by emitting alpha particles with a half-life of about 10 minutes. Not occurring in nature, nobelium was first claimed by an international team of scientists working at the Nobel Institute of Physics in Stockholm in 1957. The element was named after Swedish chemist Alfred Nobel.
