Resumen:
K-shell vacancy production cross sections due to ionization process are measured using x-ray technique, in collisions of highly charged F ions with various solid targets such as, Cl, K, Fe and Cu, at energies from 50 to 110 MeV. The experimental data is compared with an ab initio model based on Local Plasma Approximation (LPA) and the usually employed ECPSSR.  A detail comparison with the LPA model is presented as a function of generalized perturbation strength.
