K-shell ionization of heavy hydrogen-like ions

Autor: Th. Stöhlker, A. N. Artemyev, Andrey Surzhykov, O. Novak, R. Kholodov

A theoretical study of the K-shell ionization of hydrogen-like ions, colliding with bare nuclei, is performed within the framework of the time-dependent Dirac equation. Special emphasis is placed on the ionization probability that is investigated as
