THE K–LL AUGER SPECTRUM OF 94Pu239

The K–LL Auger spectrum of 94Pu239 has been examined using a high resolution π√2 β-ray spectrometer with a proportional counter detector. Seven lines have been observed in the Auger spectrum with the following energies and relative intensities.[Formula: see text]The presence of seven lines in this K–LL Auger spectrum is in disagreement with theoretical predictions based on pure j–j coupling and supports, rather, the recent theoretical treatment of Asaad and Burhop. The energies of the observed lines are in satisfactory agreement with their theoretical predictions but discrepancies exist in the relative intensities.
