The probability of double {ital K}-shell vacancy production in the electron capture decay of {sup 139}Ce to the 166-keV level of {sup 139}La has been investigated. Triple coincidences between the 166-keV gamma ray, the La satellite {ital K}{alpha} x ray, and the La hypersatellite {ital K}{alpha} x ray were measured using two intrinsic Ge detectors. We looked for the sum of two of the three radiations in one detector in coincidence with the third radiation in the other detector. The probability of double {ital K}-shell vacancy production per {ital K}-shell electron capture ({ital P}{sub {ital K}{ital K}}) was found to be (2.0{plus minus}1.6){times}10{sup {minus}6}. From this and the known {ital P}{sub {ital K}{ital K}} for {sup 131}Cs we estimate a probability for zero {ital K}-shell vacancy production (shakedown) per {ital K}-shell electron capture of {approx lt}2.4{times}10{sup {minus}5} for {sup 139}Ce.
