Double ionization of the atomic K shell accompanying the K-shell internal conversion of the 0.145-MeV transition of /sup 141/Pr has been studied by recording coincidences between K..cap alpha.. satellite x rays and K..cap alpha.. hypersatellite x rays emitted when the double vacancies are filled. The probability per K-shell internal conversion that a double vacancy is formed, P/sub K/K(IC), was found to be (3.4 +- 0.3) x 10/sup -5/, which is a factor of (0.79 +- 0.07) times the theoretical prediction for K-shell electron shakeoff in K-shell internal conversion of Mukoyama and Shimizu. The K..cap alpha../sub 1/ to K..cap alpha../sub 2/ hyper- satellite ratio was found to be (1.50 +- 0.13), a value which is about 6% less than the calculation of Aberg et al.
