Double K-shell-vacancy production in the decay of /sup 114m/In

The probability P/sub K/K of double K-shell-vacancy production per K-shell internal conversion of the 192-keV E4 transition in the decay of /sup 114m/In has been determined by means of a hypersatellite K..cap alpha../sup H/-x-ray--K-x-ray coincidence experiment using an intrinsic Ge and a NaI(Tl) detector, and by means of a direct measurement of the K..cap alpha../sup H//sub 1/- and K..cap alpha../sup H//sub 2/-x-ray components with a curved-crystal spectrometer. The results are in good agreement: P/sub K/K = (10.8 +- 0.9) x 10/sup -5/ and P/sub K/K = (9.6 +- 0.8) x 10/sup -5/, respectively. The average value is P/sub K/K = (10.2 +- 0.6) x 10/sup -5/. For the intensity ratio of the K..cap alpha../sup H//sub 1/- and K..cap alpha../sup H//sub 2/-x-ray components we obtained 1.57 +- 0.17, and for the energy shifts of the two components we obtained, respectively, 566.8 +- 1.4 and 560.2 +- 1.3 eV.
