Study of the Szilard-Chalmers effect on potassium ferrocyanide; Etude de l'effet Szilard-Chalmers sur le ferrocyanure de potassium

Abstract

Irradiation conditions and a simple chemical treatment are described, for obtaining from potassium ferrocyanide the mixture {sup 55}Fe, {sup 59}Fe with a high specific activity. The recoil behaviour of the two isotopes is shown to be different: because of its greater energy {sup 55}Fe will be enriched by extraction of the ejected atoms from the rest of the molecule. An attempt is made to explain the increase in retention as proportional to the decrease in specific activity. (author) [French] Les conditions d'irradiation du ferrocyanure de potassium et un traitement chimique simple sont donnes pour permettre l'obtention du melange {sup 55}Fe, {sup 59}Fe de grande activite specifique. On a mis en evidence une difference de comportement des deux isotopes sous l'effet de recul; l'energie plus grande du {sup 55}Fe permettant son enrichissement par extraction des atomes ejectes du reste de la molecule. Un essai d'explication de l'augmentation de la retention proportionnellement a la diminution de l'activite specifique est donne. (auteur)
