Abstract
THIS little book on the elements of the rare earth group, or lanthanides as they are now called, contains chapters on (a) electronic structures and oxidation states, (b) magnetic properties, (c) absorption spectra, (d) evidence for the existence of element No. 61, (e) separation of the rare earths, and (f) chemical and physical properties of these elements. There is also an appendix on nuclear properties of the rare earth elements. Since the chapters noted above cover only 69 pages, it is inevitable that the subject-matter has been very much condensed, a fact more evident in descriptions of chemical than physical properties. Apart from this limitation, the volume contains much useful and interesting information about this group of elements. The rare earths have received more attention from chemists following the discovery that some of them are formed directly or indirectly in nuclear disintegrations. This book provides a useful introduction to the study of a very interesting series of the chemical elements.
