The inner-shell ionization cross sections in ion-atom collisions have been calculated with the finite-base-set expansion method, using expansion into atomic orbitals and pseudostates. The calculations have been made within the framework of the impact-parameter formalism and the distortion approximation has been used. The obtained cross sections are in good agreement with the experimental results. The extension of the method to the relativistic case has been attempted and good agreement with the measured results is achieved.
