Cerium nuclear properties

The last of the lanthanides, this metal is also the hardest and the densest of them. It is a component of cerium mischmetal. Lutetium has some applications in optoelectronics. Shows great similarities to ytterbium. Its discoverer, Georges Urbain, carried out 15 000 fractional crystallizations to isolate pure lutetium (record ). The element has special catalytic properties (oil industry). 176Lu is generated artificially and is a good beta emitter (research purposes). 177Lu has a half-life of six days and is used in nuclear medicine. 

Cerium, an element in the lanthanide series, has a number of radioactive isotopes. Several of these are produced in abundance in nuclear fission reactions associated with nuclear industry operations or detonation of nuclear devices. This report summarizes our present knowledge of the relevant physical, chemical, and biological properties of radiocerium as a basis for establishing radiation protection guidelines. 

Tm). The high thermal neutron absorption cross-sections and high melting points of various lanthanides (Sm, Eu, Dy, Gd) are two properties that make them ideal for use in nuclear reactor control rod applications. Cerium dioxide has been developed into a sunscreen that has higher transparency and higher ultraviolet blocking proper-... 

The only elements that have no stable isotope with a nuclear spin are cerium and argon, but there are others for which no spectra have been reported, including gold, which is 100% Au, with 7=3/2. There is a full discussion of the applications of NMR to all the less commonly observed elements in [1]. Although it was published as long ago as 1978, this is still an essential reference book for those interested in applying NMR widely in inorganic chemistry. Properties of some isotopes with /> 1/2 are included in Table 4.1.
