Charge-state dependence of fluorineKx rays in F-Ne collisions

The $K$ x-ray-production cross sections for fluorine are measured as a function of charge state for 15-MeV ${\mathrm{F}}^{q+}+\mathrm{Ne}$ collisions. The measurements are differential in energy of the $K$ x rays with sufficient resolution to identify the final-state configurations of the fluorine ions following the collision. The final states are identified with the processes of single $K$-shell to $L$-shell excitation, single $K$-shell - multiple $L$-shell ionization, and single $L$-shell electron capture.
