✦ Synopsis
Including lanthanum, fifteen chemically similar elements between barium and hafnium on the periodic table are known as rare earth elements. This region has been the least investigated by the spectroscopists. The book at hand presents the principal chemical and physical properties of the rare earth elements and their compounds, and shows the concordance of the current theories with these properties. The six chapter headings are indicative of the coverage. They are Electronic Structures and Oxidation States of the Rare Earth Elements, Paramagnetic Properties of Rare Earth Compounds, Absorption Spectra of Rare Earth Compounds, Evidence For the Existance of Element 61, Separation of Rare Earths, and Chemical and Physical Properties of the Rare Earths. The appendices are Nuclear Properties of the Rare Earth Elements, General Physical Constants, and The Periodic System of the Elements. Many references are made to the literature. In the back are name and subject indexes. This 86-page treatment contains a fund of information digested from various sources and coupled with expert knowledge of the authors. R. H. OPPERMANN.
