Electron angular distributions in the two--photon ionization of hydrogen--like ions: relativistic description
Peter Koval, Stephan Fritzsche, Andrey Surzhykov
The angular distribution of the emitted electrons, following the two--photon ionization of the hydrogen--like ions, is studied within the framework of second order perturbation the…
Relativistic and retardation effects in the two--photon ionization of hydrogen--like ions
Peter Koval, Stephan Fritzsche, Andrey Surzhykov
The non-resonant two-photon ionization of hydrogen-like ions is studied in second-order perturbation theory, based on the Dirac equation. To carry out the summation over the comple…
Relativistic wave and Green's functions for hydrogen--like ions
Peter Koval, Stephan Fritzsche
The \textsc{Greens} library is presented which provides a set of C++ procedures for the computation of the (radial) Coulomb wave and Green's functions. Both, the nonrelativistic as…
