Abstract Projectile and targetK-shell ionization cross sections induced by 3.6-, 4.7-, and 5.9 MeV/u132Xe ions and 1.4-, 3.6-, 4.7-, and 5.9 MeV/u208Pb ions from the UNILAC in thin solid targets between C and U are measured. The cross sections are discussed in terms of the molecular model of innershell vacancy production in heavy ion-atom collisions. The sharing of 2p 1/2σ vacancies between theK shells of the two collision partners in these very heavy ion-atom collisions is found to deviate from the Meyerhof-Demkov formula forR≦10−2. The measured ionization cross sections are compared with theoretical calculations for 1sσ and 2p 1/2σ excitation cross sections. AZ UA=Z1+Z 2 dependence is found independent ofZ 1/Z 2. Outer-shell vacancy configurations measured in these close encounters are reported.
