The energy systematics of single and double K-shell-vacancy production in titanium have been investigated near the limit of zero target thickness for incident chlorine ions over an energy range of 7--15 MeV/amu. Single and double K-shell-vacancy production cross sections have been measured for projectiles incident with zero, one, and two initial K-shell vacancies. Single and double K-shell-to-K-shell electron-transfer cross sections have been obtained indirectly using differencing procedures based on the projectile-charge-state dependence of single and double K-shell-vacancy production. The measured cross sections have been compared to theoretical models for direct ionization and inner-shell electron transfer. Together with previously reported data, these cross sections also have been used to investigate the relative importance of these mechanisms for K-shell-vacancy production in heavy-ion--atom collisions over a range of scaled velocities of 0.24< or =V/sub 1//V/sub 2K/< or =1.29.
