摘要：

Ionization of highly charged relativistic ions by neutral atoms and ions is considered. Numerical results of recently developed computer codes based on the plane-wave Born and the equivalent-photon approximations are presented and compared with experimental data available at relativistic energies for 1s electron ionization. New formulas for relativistic cross sections are derived for ionization of the projectile electron with arbitrary quantum numbers n and l. The results are obtained on the basis of the nonrelativistic reduction in the Dirac matrix element.
