Excited levels in Bi 206 from the decay of Po 206

Abstract

The energies and intensities of conversion electrons from the decay of Po 206 have been studied in a double focusing beta-spectrometer. Relative gamma intensities were measured in a scintillation spectrometer. Coincidences between pairs of conversion lines were studied in a coincidence spectrometer. No positons were observed. A decay scheme is proposed, which contains 9 excited levels and includes 20 of the observed transitions.
