✦ Synopsis

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 di †erent high-resolution curved crystal spectrometers of reÑectiontype geometry. From the Ðrst measurements performed at the Paul Scherrer Institute (PSI), only an upper limit of 0.25% relatively to the intensity of the diagram line could be obtained for the total KÈLM RA yield. From Ka 1,2 a second experiment carried out at the University of Fribourg, a I(K-LM ratio of 0.18 » 0.05% was RA)/I(Ka 1,2 ) 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.
