Abstract
The energy spectrum of a rare-earth impurity in a normal metal is considered. It is possible to achieve the degeneration of the magnetic energy sublevels of the impurity under an external magnetic field. This degeneration gives the anomalous Kondo scattering of conduction electrons. In the region of weak coupling, the amplitude of scattering and the contribution of this mechanism to the electroresistance of the metal are calculated. The effect of conduction-electron scattering on the impurity couples is considered. The influence of Landau quantisation on the effect is studied. It is shown that the investigation of Kondo anomalies can be used as a tool to obtain information about crystal fields in metals.
