The inner-shell ionization cross sections in ion-atom collisions have been calculated by the finite-basis-set expansion method. The atomic wave functions are represented in terms of Slater-type orbitals to diagonalize the atomic Hamiltonian. The obtained atomic orbitals and pseudostates are used to calculate the inner-shell ionization cross sections within the framework of the impact-parameter approach. The calculated cross sections in the distortion approximation are in good agreement with the experimental data. The extension to the relativistic case has been attempted and good agreement is achieved between the calculated and measured results.
