The K Auger electron spectra have been measured for boron and fluorine bombarded with C2+ , N2+ and O2+ ions at 0.75-2.50 MeV impact energies. Those for N2+ and O2+ in the cases of the F+N2+ and F+O2+ impacts have also been measured. The derived cross sections for K shell excitation have agreed well with the MO model theories of Taulbjerg et ah and Meyerhof. The results support that the 2p vacancies of both colliding partners mixingly contribute to the cross section. The K shell ionization cross sections have been derived for both target atoms excited by protons and alpha particles, the results of which being generally consistent with the theories of plane wave Born approximation and binary encounter approximation.
