Abstract: 
Absolute cross sections for electron-impact single ionization of potassium-like titanium have been measured from threshold to 1000 eV using a crossed-beams experimental set-up. A 0.5 eV resolution energy-scan technique revealed structures in the cross section in the range from 40 eV to 150 eV due to dominant contributions of indirect ionization mechanisms. A large fraction of the cross section is due to excitation-autoionization proceeding via intermediate excited states 3p(5) (3d(2) F-3) F-2, 3p(5)(3d(2) P-3) (2)p, (3)p(5) (3d(2 3)F) D-2 which subsequently decay by super-Coster-Kronig transitions. The results of the measurements are in satisfactory agreement with previous advanced theoretical calculations.
