ResumoImpact-parameter-dependent probabilities of $K$ and $L$ characteristic x-ray production in collisions of 45-, 94-, and 138-MeV $_{28}^{58}\mathrm{Ni}$ ions with solid targets of $_{25}\mathrm{Mn}$, $_{50}\mathrm{Sn}$, and $_{82}\mathrm{Pb}$ were measured. The results are compared with predictions of the statistical and the molecular-orbital models for inner-shell vacancy production. A short development of the statistical model in a random-walk approximation is given to display the physical content of the model in simple terms.
