X-Ray Production and Electron Transfer Cross Sections for 0.4-2.2 MeV/amu N, O, and F Ions on A1

In 1972 the observations of strong charge-state dependences of target K x-ray production for heavy ions incident upon thin gas targets were reported.1'2 These charge state dependences were associated with target K-shell to projectile K-shell electron transfer3 and with target fluorescence yields due to multiple ionization.4 Similar observations have been reported for heavy ions incident upon solids where the production of target x rays is measured as a function of target thickness.5'6'' Gardner et al.7 formulated the three component model for target K x-ray production which relates the effects of ions moving in the solid target with 0, 1 and 2 K-shell vacancies to the target x-ray yield as a function of target thickness. The basis of the three-component model is the integral expression for the target K x-ray yield (oKX) given in units of cross section, T
