Loss of electrons from fast heavy structure ions colliding with atoms

Nonperturbative theory is developed for the multiple ionization of fast heavy structure ions colliding with neutral complex atoms. The cross sections for multiple loss of electrons by structure uranium ions U¹⁰⁺ (loss of up to 82 electrons) and U²⁸⁺ (loss of up to 64 electrons) colliding with argon atoms are calculated. The results are compared with available experimental data.
