Conversion of the 42 keV transition in the decay of191Os

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

Summary

The total as well as theL-conversion coefficient of the 42 keV transition in the decay of191Os are determined from intensity balance considerations and XPG technique, respectively, using a 3 mm Si(Li) detector system. The resultant values are αT = 13709 (1900), αL = 11700 (2100). The present total conversion coefficient shows good agreement within the uncertainty limits, with the value αT = 13.500 +21100−5200 reported by Lange, whereas theL-conversion coefficient is reported for the first time. Our present values are also compared with the theoretical values interpolated from the tables of Hager and Seltzer and of Roselet al.

Riassunto

Si determinano il coefficiente totale e quello di conversioneL della transizione a 42 keV nel decadimento di191Os considerando il bilancio d’intensità e la tecnica XPG, rispettivamente, usando un sistema di rivelatori a 3 mm Si(Li). I valori risultanti sono αT = 13709 (1900), αL = 11700 (2100). Il coefficinete di conversione totale è in buon accordo, entro i limiti di incertezza, con il valore αT = 13.500 +21100−5200 riportato da Lange, mentre il coefficiente di conversioneL è riportato per la prima volta. I nostri valori attuali sono anche confrontati con i valori teorici interpolati dalle tavole di Hager e Seltzer e di Roselet al.
