The classical binary-encounter model for the ionization of ions by impact of electrons given by Thomas and Garcia has been extended to calculate the excitation cross section of ions. The electron-impact excitation cross sections for the 3s-3p and the 3s-3d transitions in Mg+, the 2s-2p transition in Be+, and the 4s-4p transition in Ca+ have been calculated. The results are compared with calculations based on the close-coupling and the Coulomb-Born approximations. Our results agree better with close-coupling calculations than with calculations based on the Coulomb-Born approximation.
