【 摘 要 】

Non-perturbative calculations of the relativistic quantum dynamics of electrons in the Xe-Xe54+collisions at 30 AMeV are performed. The calculations are based on an independent-electron model and use the coupled-channel approach with atomic-like Dirac-Fock-Sturm orbitals. Special attention is paid to the inner-shell processes. The role of the relativistic and many-particle effects is studied.
