Abstract

On applique la technique d'analyse par activation neutronique non destructive, utilisant un détecteur Ge(Li) à haute résolution pour déterminer des traces d'impuretés dans des diamants. La présence de 40 éléments est mise en évidence dans les diamants naturels. On donne des résultats quantitatifs portant sur 13 éléments dans 25 échantillons de diamant représentatifs d'une même origine. Un rapport a été établi entre la chimie des inclusions et la couleur des diamants d'une part, et les traces des éléments trouvés d'autre part.
