The 1s −2 Auger hypersatellite spectrum of argon is studied experimentally and theoretically. In total, three transitions to the final states 1s −12p −2(2 S e ,2 D e ) and 1s −12s −1(1 S)2p −1(2 P o ) are experimentally observed. The lifetime broadening of the 1s −2 → 1s −12p −2(2 S e ,2 D e ) states is determined to be 2.1(4) eV. For the used photon energy of = 7500 eV a KK/K ionisation ratio of 2.5(3) 10−4 is derived. Generally, a good agreement between the experimental and present theoretical energy positions, linewidths, and intensities is obtained.
