Abstract
The exact solution of the degenerate exchange model describing Kondo alloys with rare-earth impurities is constructed on the basis of the Bethe ansatz technique. The ratio of heat capacity to magnetic susceptibility at T=0 is obtained for alloys where the Kondo temperature greatly exceeds the crystal field.
