Double K-hole creation has been studied in the electron-capture decay of /sup 131/Cs by measuring hypersatellite K x rays emitted when the double vacancies of the K shell are filled. The complex K lines observed with a two-Ge-detector coincidence spectrometer show evidence of the hypersatellite K..cap alpha.. and K..beta.. lines. The double K-hole creation probability is determined: (1.4 +- 0.1) x 10/sup -5/ per K-capture event. This value, which does not agree with theoretical predictions, is discussed in detail. The intensity ratio of the K..cap alpha../sub 1/ to K..cap alpha../sub 2/ hypersatellites is found to be 1.5 +- 0.2. The intensity of internal bremsstrahlung photons accompanying the K-electron capture decay has also been reevaluated.
