Calculations employing the independent-electron approximation suggest that direct Coulomb ionization is the dominant mechanism for Ar {ital K}-vacancy production by 47-MeV Ca{sup 17+}, rather than {ital K}-{ital K} vacancy sharing as proposed by Schlachter {ital et} {ital al}. (J. Phys. B 21, L291 (1988)). Using electron-capture probabilities for zero impact parameter given by the classical-trajectory Monte Carlo model, good agreement with the experimental charge-state distribution for multielectron capture in coincidence with Ar and Ca {ital K} x rays is achieved.
