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…
