Abstract
Les composantes monopolaires et dipolaires du gradient de champ électrique au niveau de l'ion Sn4+ ont été calculées pour les structures SnO2 et SnF4. La comparaison avec les résultats de spectroscopie Môssbauer (éclatement quadrupolaire) conduit aux valeurs suivantes de la polarisabilité : α(O=) = 1,60 Å3 et α(F -) = 0,98 Å3Keywords
