Relativistic calculations of inner-shell atomic processes in low-energy ion–atom collisions

Abstract

Relativistic calculations of inner-shell atomic processes in low-energy Ne–F8+(1s) and Xe–Xe53+(1s) collisions are performed. The method of calculation exploits the active-electron approximation and is based on the coupled-channel approach with atomic-like Dirac–Sturm–Fock orbitals, localized at the ions (atoms). The screening density-functional theory is applied for description of the interaction with passive electrons. The role of relativistic effects is analyzed.
