Wichmann-Kroll Correction to the Interelectronic Interaction in He- and Li-Like Ions
J. Sommerfeldt, V. A. Yerokhin, Z. Harman +1
We present a theoretical study of the higher-order QED contribution to the interelectronic interaction in He- and Li-like ions, where a virtual electron-positron loop is inserted i…
Bound-state Compton scattering of linearly polarized photons
Jonas Sommerfeldt, Nick M. Mayer, Anna Maiorova +4
We present a theoretical study of Compton scattering of X- and -rays by a -shell electron. Special attention is paid to the double-differential cross section and polarization…
Delbrück scattering above the pair production threshold: Going beyond the Born approximation
J. Sommerfeldt, V. A. Yerokhin, A. Surzhykov
We present a theoretical method to calculate Delbrück scattering amplitudes for photon energies above the electron-positron pair production threshold. The method is based on the ap…
Low-energy tests of Delbrück scattering
J. Sommerfeldt, S. Strnat, V. A. Yerokhin +3
We present a theoretical study of elastic photon scattering by atomic targets. This process is of special interest since various channels from atomic and nuclear physics as well as…
All-order Coulomb corrections to Delbrück scattering above the pair production threshold
J. Sommerfeldt, V. A. Yerokhin, Th. Stöhlker +1
We report calculations of Delbrück scattering that include all-order Coulomb corrections for photon energies above the threshold of electron-positron pair creation. Our approach is…
Excitation and probing of low-energy nuclear states at high-energy storage rings
Junlan Jin, Hendrik Bekker, Tobias Kirschbaum +6
Th with a low-lying nuclear isomeric state is an essential candidate for a nuclear clock as well as many other applications. Laser excitation of the isomeric state has been…
