160Tb decay

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

By means of an intermediate ß spectrometer and a scintillation spectrometer, the decay of160Tb has been studied. Coincidences between β- continuous spectrum and selected λ-rays allows the resolution of the β- spectra of low energy. β- spectra of 367 ± 12, 564 ± 6.5, 861 ± 1.8, and 1711±7keV have been resolved. From their photo-spectrum relative intensities of γ-rays have been taken. Conversion coefficients of some γ-rays have been obtained. A decay scheme is suggested. The possibility of the rotational character of some of the excited levels, predicted by the Bohr-Mottelson theory, is discussed.

Riassunto

Il decadimento del160Tb e del160Dy è stato studiato mediante uno spettrografo β ad immagine intermedia e mediante uno spettrometro a scintillazione. La componente β- di bassa energia è stata accuratamente risolta mediante studi di coincidenze. I coeffloienti di conversione interna di alcune transizioni sono stati ottenuti dagli spettri di conversione interna ed esterna. Si propone uno schema di decadimento consistente con i risultati sperimentali.
