The present study was undertaken to determine the direct ionization and electron capture contributions to vacancy production in the M-shells of /sub 79/Au, /sub 82/Pb, /sub 83/Bi and /sub 92/U for incident /sup 19//sub 9/F ions. M-shell x-ray production cross sections have been measured for 1.42-MeV/amu /sup 19//sub 9/Fq/sup +/ ions for q = 4,5,6,8,9. Enhancements in the target x-ray production cross sections were observed for projectiles with one and two K-shell vacancies over those without K-shell vacancies. Direct ionization and electron capture contributions to the vacancy production were extracted from the data and compared to the plane wave Born approximation and to the Oppenheimer-Brinkman-Kramers calculations of Nikolaev, respectively.
