Solvent extraction of rare earths

Since Gd has no orbital magnetic moment, and accordingly exhibits only a small anisotropy, an introduction of an anisotropic rare earth ions changes the

We have experimentally determined the occupied 4 f energy levels in a number of rare earth metals, namely the following ones, Nd, Sm, Eu, Gd, Dy, Er, and Yb using

— The study of the correspondence between the solutions of the equations of Dirac and Schrodinger leads to the necessity of retaining in the case of Schrodinger, positive and

Thus straggling free range can be estimated by using equation (3). — A) Comparison of theoretical projected ranges in mg/cm 2 and ratio or ranges for 1.77 MeV electrons and 1.88

We have now extended this work to include two other rare-earth solute elements with rather special characteristics : Ce, where incipient 4f-conduction electron

The experimental resistivity data of liquid rare earths (RE) shows the following behavior [l, 21 : The resistivity p increases across the series of the trivalent

Thus, decreasing solvent polarity also reduces water-crown complexation [L‚H 2 O (org) ], leading to lower k values. This is probably caused by the combination of a lower solubility

In the dilute alloys studied exchange interactions are small perturbations on the crystal field and the exchange can be adequately treated in the molecular
