Description

The total conversion coefficient of the 6.2 keV Moessbauer transition in 181Ta was measured by X- and gamma-ray spectroscopy. The result of 86 +- 20 disagrees with the literature value of 46, but agrees with theory if a nuclear penetration parameter deduced from relative conversion electron intensities is taken into account. The weak 6.2 keV gamma ray has intensity per decay that is less than the previous value by a factor of 8.5. (orig.)

Abstract (German)

Der totale Konversionskoeffizient des 6,2 keV-Moessbauer-Uebergangs in 181Ta wurde durch Roentgen- und γ-Spektroskopie gemessen. Das Ergebnis von 86 +- 20 weicht von dem in der Literatur angegebenen Wert von 46 ab; es stimmt jedoch mit der Theorie ueberein, wenn ein Parameter fuer Kernpenetration beruecksichtigt wird, der aus den relativen Intensitaeten der Konversionselektronen abgeleitet wurde. Die Intensitaet pro Zerfall des schwachen 6,2 keV γ-Strahls ist um einen Faktor 8,5 kleiner als der fruehere Wert. (orig./AK)
