As shown in papers I and II of this series, far from symmetry the K-vacancy production cross section of the lower-Z (Z/sub L/) partner in heavy-ion collisions varies rapidly with the atomic number Z/sub H/ of the higher-Z partner. We examine our and other data for K and L x-ray production with 45-94-MeV Ni, 45-110-MeV Br, 47- and 62-MeV I projectiles and interpret the Z/sub L/ K-vacancy production far from symmetry in terms of the K-L level matching mechanism of Barat and Lichten. Sharing of 3dsigma vacancies on the outgoing part of the collision provides a semiquantitative understanding of the dependence of K and L cross sections on Z/sub L/, Z/sub H/, and bombarding energy. Some remarks about the general role of vacancy sharing in inner-shell vacancy formation in heavy-ion collisions are made.
