The energy shifts of Kbeta X-rays and the Kbeta/ Kalpha intensity ratios by 2.8 MeV N+-ion bombardments have been measured for eight elements from Ti to Ge. The Kbeta/K alpha ratios are expressed as relative values to the ratios for 2 MeV proton impact. The experimental results indicate single K- plus multiple L- and M-shell ionisation, and strongly reflect the relative importance of M-shell vacancies in the Kbeta/Kalpha ratios at the time of K X-ray emission. These data are compared with the Hartree-Fock-Slater calculations and used to deduce information about the vacancy configurations of ionised atoms. The present results can be qualitatively explained within the framework of the direct Coulomb ionisation theory.
