L..cap alpha.. x-ray-production cross sections have been measured for solid targets of /sub 60/Nd, /sub 67/Ho, and /sub 79/Au for 1.86-MeV/amu /sup 19//sub 9/F and /sup 28//sub 14/Si, and 1.8-MeV/amu /sup 35//sub 17/Cl ions as a function of the incident charge state. From the projectile-charge-state dependence of the cross sections, both direct-ionization and electron-capture contributions were extracted for a comparison to Coulomb ionization theories. The data provide supporting evidence for the theory of electron capture with a reduced binding effect. With standard fluorescence and Coster-Kronig yields uncorrected for multiple-ionization effects, the direct ionization theories did not simultaneously reproduce the projectile-Z/sub 1/ and target-Z/sub 2/ dependences of the data.
