curium

curium
curium curium n. [after Pierre and Marie Curie.] a radioactive transuranic element of atomic number 96, having an atomic weight of 247 for its most stable isotope (half-life 1.6 x 10^{7} years). The chemical symbol is Cm.

Note: It was first prepared in 1944 by helium-ion bombardment of plutonium in a cyclotron by Glenn Seaborg and colleagues in California. It has never been detected in nature, though minute quantities may exist in uranium deposits as a consequence of the neutron flux there.

Syn: Cm, atomic number 96. [WordNet 1.5]
