The name of element 104. The artificial synthesis of element 104 was first reported in 1964 at the Dubna Institute of Nuclear Research in the Soviet Union, and a group of Soviet researchers advocated the use of the name kurchatovium and the element symbol Ku. However, shortly thereafter, a group of American researchers criticized this, and there has been a battle for leadership over the discovery between the Soviet and American groups. The American group advocates the use of the name rutherfordium and the element symbol Rf. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
104番元素の元素名。はじめ1964年ソ連のドゥブナ原子核研究所で,104番元素を人工的に合成したことが報告され,これについてソ連の研究者グループはクルチャトビウムという名称とKuという元素記号の採用を主張した。しかし,その後まもなく,これに対するアメリカの研究者グループの批判があり,その発見についてはソ連とアメリカの研究者グループ間で主導権争いがなされてきた。アメリカのグループはラザフォージウムrutherfordiumという名称とRfという元素記号の採用を主張している。
