Zusammenfassung
Die relativen Empfindlichkeitsfaktoren für die Elemente Ce, Nd, Sm, Eu, Gd, Dy, Er und Lu in U3O8 wurden mit der Funken-Massenspektrometrie mit elektrischem Nachweis (peak switching) bestimmt. Früher sind diese Faktoren in Uranylnitrat bestimmt worden und es wurde erwartet, daß trotz unterschiedlicher absoluter Werte der Trend derselbe wäre. Es zeigte sich jedoch, daß auch der Trend verschieden ist. Die Werte der vorliegenden Untersuchung stimmen mit theoretischen Berechnungen aus den Zersetzungsenergien der Seltenerdoxide überein und bestätigen die Ergebnisse anderer Autoren für die Y2O3-Matrix.
Summary
Relative Sensitivity Factors (RSFs) for the rare earth elements Ce, Nd, Sm, Eu, Gd, Dy, Er and Lu in U3O8 have been determined by Spark Source Mass Spectrometry (SSMS) using the electrical detection system in peak switching mode. Earlier RSFs for these elements were determined in uranyl nitrate and it was expected that though the absolute value of the RSFs may be different, the trend would be the same. However, the present work shows that apart from the magnitude, the trend in RSF values is also different. The data from the present work are in agreement with the theoretical calculations based on the decomposition energies of the rare earth oxides and support the work carried out by others in the case of Y2O3 matrix.
