The K–LM radiative Auger (RA) x‐ray spectrum of argon was observed. The transitions were photoinduced by means of an x‐ray tube and measured with two different high‐resolution curved crystal spectrometers of reflection‐type geometry. From the first measurements performed at the Paul Scherrer Institute (PSI), only an upper limit of 0.25% relatively to the intensity of the Kα 1,2 diagram line could be obtained for the total K—LM RA yield. From a second experiment carried out at the University of Fribourg, a I (K–LM RA)/ I (Kα 1,2 ) ratio of 0.18±0.05% was obtained. This value is consistent with the PSI result but in strong disagreement with theoretical predictions based on the shake model, which are about four times larger. © 1998 John Wiley & Sons, Ltd.
