PARTIAL QUADRUPOLE SPLITTING OF Fe-57 SPECIES PRODUCED FROM Co-57-LABELLED WERNER COMPLEXES

Les valeurs de l'effet quadrupolaire résultant du processus 57Co(CE) 57Fe ont été mesurées dans des composés de coordinences variées du type Werner marqués au 57Co. Une des deux composantes trouvées dans le spectre Mössbauer d'émission a été attribuée à des états haut spin produits après le processus de conversion électronique. L'autre composante a été attribuée à des états 57Fe(III).The quadrupole splitting values of the species produced from the 57Co(EC) 57Fe process were investigated in the various 57Co-labelled Werner-type co-ordination compounds. One of the two components of the decayed species found in the emission Mössbauer spectra was assigned to high-spin species of Fe(II) produced after the EC-decay based on their large quadrupole splittings and isomer shifts. The other component was ascribed to co-ordinated 57Fe(III) species, since the quadrupole splittings of the species were well represented by using the partial quadrupole splitting of each ligand
