K β /K α X-ray intensity ratio followingK-electron capture and radioisotope excitation

ОтнощениеK β /K α интенсивностей рентгеновского иэлучения после K-эахвата и воэбуждения радиоиэотопов

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

TheK β /K α X-ray intensity ratios are measured for Mn and Fe and for six other elements withZ lying in the range 49⩽Z⩽82 following electron capture decay and photon excitation using241Am and57Co sources. High-resolution Si(Li) and HpGe detector systems were used in the experiments. The dependence ofK β /K α values on the mode of excitation in the case of Mn and Fe is attributed to chemical effects, while no such dependence is found for the high-Z elements.

Riassunto

Si misurano i rapportiK β /K α d’intensità dei raggi X per Mn e Fe e per altri 6 elementi aventiZ nell’intervallo 49⩽Z⩽82 che seguono il decadimento di cattura dell’elettrone e l’eccitazione fotonica usando le sorgenti231Am e57Co. Si usano negli esperimenti sistemi di rivelatori Si(Li) e HpGe ad alta risoluzione. Si attribuisce la dipendenza dei valori diK β /K α dal modo di eccitazione nel caso di Mn e Fe ad effetti chi mici, mentre non si trova una dipendenza di questo tipo negli elementi conZ grande.

Реэюме

Иэмеряются отнощенияK β /K α интенсивностей рентгеновского иэлу-чения для Мn и Fе и для щести других злементов сZ в области 49⩽Z⩽82 послеK-эахвата и фотонного воэбуждения, испольэуя источники241Am и57Co. В зкспери-ментах испольэуются системы детектирования с высоким раэрещением Si(Li) и НрСе. Зависимость величинK β /K α от моды воэбуждения в случае Мп и Ее при-писывается химическим зффектам, тогда как для злементов с больщимиZ такая эависимость не обнаружена.
