From The Collaborative International Dictionary of English v.0.44 [gcide]:
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]
From WordNet (r) 2.0 [wn]:
curium
noun: a radioactive transuranic metallic element; produced by bombarding plutonium with helium nuclei [syn: {Cm}, {atomic number 96}]
From Elements database 20001107 [elements]:
curium Symbol: Cm Atomic number: 96 Atomic weight: (247) Radioactive metallic transuranic element. Belongs to actinoid series. Nine known isotopes, Cm-247 has a half-life of 1.64*10^7 years. First identified by Glenn T. Seaborg and associates in 1944, first produced by L.B. Werner and I. Perlman in 1947 by bombarding americium-241 with {neutron}s. Named for Marie Curie.
