Double Focusing

The low energy levels of 197Au and 199Au have been investigated by means of a high resolution double focusing beta-ray spectrometer. The conversion electron ratios as well as the K-conversion coefficients of low-lying transitions were determined. The K-internal conversion coefficients of the 191 keV transition in 197Au indicated no EO contribution. The level structure of the lower excited states in 197Au and 199Au are discussed in terms of existing nuclear models.

Good Agreement

The X-ray spectra resulting from the internal conversion of electric quadrupole transitions following the alpha decay of Th230 and Ra226 were analysed with a Si (Li) spectrometer. From the knowledge of the Coster-Kronig and fluorescence yields, the internal conversion coefficients of the E2 transitions from the first excited states in Ra226 and Rn222 could be deduced. Results are in good agreement with theoretical values.
