Projectile K-Auger production cross sections for fluorine
The K-Auger electron production cross sections of fluorine produced in collisions with thin helium and neon gas targets were obtained for incident fluorine ions of charge states q = +2 to q = +8 and incident energies of 6, 9, 12, and 15 MeV. The cross sections were measured with an electrostatic cylindrical mirror electron analyzer. The Auger transitions for the lower charge states (q less than or equal to 5) were from fluorine states created by ionization and excitation but, for q = 6, were from fluorine states created solely by excitation. For the higher charge states (q = 7,8) single and double electron capture to excited states was the process leading to the creation of the fluorine states observed by Auger decay. Partial K-Auger production cross sections for fluorine states created by simple capture of a single electron to a specific n level of the projectile were obtained and compared to the predicted n dependence of an OBK calculation and an eikonal approach to electron capture. The effects of cascading were also investigated.
