Abstract
We show that a satisfactory fit to the temperature dependence of the relaxation rate of ytterbium in palladium can be obtained by including the aspherical part of the direct Coulomb interaction between 4f electrons and the d part of the conduction electrons.
Résumé
Nous montrons que l'on peut expliquer de façon satisfaisante la dépendance en température de la relaxation de Yb3+ dans le palladium en tenant compte de la partie non sphérique de l'interaction Coulombienne directe entre électrons 4f et électrons de conduction de caractère d.
