Rare-Earth and Transuranic Elements

Physical Review, 1941
Verf. zeigt das starke Absinken der Energie und das Schrumpfen der räumlichen Ausdehnung der \(4f\)- bzw. \(5f\)-Eigenfunktion beim Überschreiten der ungefähren Kernladungszahl \(Z = 57\) bzw. \(Z = 92\). Dieses Vorkommnis bedeutet, daß von diesen Ordnungszahlen ab die \(4f\)- bzw. \(5f\)-Bahnen zu inneren Elektronenbahnen werden.

The Rare-earth Elements

1971
Mossbauer spectroscopy of the rare-earth elements as a group has gained considerable attention from physicists. Successive addition of 4f-electrons along the series has little influence on many of the chemical properties, which are mainly those of a tripositive cation.

The rare earth elements

1992
They fall into two well-defined groups, the first occurring naturally in reasonably large quantities, the second being radioactive and very largely man-made short life elements. A third group resemble the rare earths to such an extent that they are always classified together.

The Rare Earth Elements

Abstract The book ends with a review of how the rare earth elements were discovered and some of the many uses that they are being put to. The 17 elements that comprise the rare earths have become extremely important and sought after commercially because of their many high-tech applications, such as in cell phones, electric vehicles, and ...
