On the decay of185W

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

The γ spectra from an electromagnetically enriched sample of184W irradiated with pile neutrons was investigated. The decay of the various radiations was followed for more than three half-lives of185W. It was ascertained that the decay of185W populates the first rotational level of185Re at 125 keV with a branching ratio of about 0.3%. TheK internal conversion of the γ-ray was found to be: 2.9 ± 0.3.

Riassunto

Si esamina lo spettro γ emesso da un campione di184W arricchito elettromagneticamente e irraggiato con neutroni termici. Il decadimento delle diverse radiazioni osservate è stato seguito per più di tre periodi di dimezzamento del185W. Si è accertata l’esistenza di una transizione β al primo livello rotazionale del185Re di 125 keV. È stato misurato il coefficiente di conversioneK della radiazione di diseccitazione e si è trovato:α K = 2.9 ± 0.3.
