Abstract The excitation conditions where both direct Coulomb and shake-off processes concur to multiply ionize fluorineK andL shells were adopted in this experiment; 6MeV/amu p,α and C4+ impacts. The ion induced FKα satellites, measured for a series of F bearing compounds, showed significant chemical effects on their intensity distributions. Such effects are explained well with an FL-vacancy rearrangement model. Without any theoretical prediction, rearrangement probabilities or widths of FL shells were estimated by use of a reference compound with high ionicity, i.e. NaF. A linear relationship between FL widths and covalencies of compounds was found for a wide variety of fluorides. For the same compounds, the absolute values of the FL-vacancy rearrangement probabilities or the FL-shell widths obtained here were the same as those estimated from pure direct Coulomb and pure shake-off excitations, respectively. Other models than theL-vacancy rearrangement's are also discussed and eliminated.
