kurchatovium \kurchatovium\ n. [From Igor Kurchatov, a Russian
scientist who worked on the atomic bomb.]
A transuranic element of atomic number 104, symbol Ku; also
called rutherfordium, symbol Rf. It is produced in very
small quantities by nuclear reactions. In November 1993 the
nomenclature committe of the American Chemical Society
approved the name rutherfordium for element 104. 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. However, investigators at Berkely in
1969 produced several isotopes of element 104 but were unable
to produce isotope 260; they reported finding isotope 257,
with a half-life of 4-5 seconds, isotope 259 with a half-life
of 3-4 seconds, and isotope 258 with a shorter half-life.
Syn: rutherfordium, Rf, Ku, unnilquadium, Unq, element 104,
atomic number 104.
