Double to tenfold M-shell photoionization of singly charged lanthanum ions
M. Looshorn, B. M. Döhring, P. -M. Hillenbrand +9
Using the photon-ion merged-beams technique at the PETRA\,III synchrotron light source, we have measured cross sections for double and up to tenfold photoionization of La ion…

Double--hole resonances in single photoionization of He-like B ions
A. Müller, P. -M. Hillenbrand, S. -X. Wang +8
Within a joint experimental and theoretical research project, single photoionization of He-like B ions was investigated in the energy range from approximately 250 to 1200~eV…

Role of the Coulomb Potential in Compton Scattering
N. Melzer, M. Kircher, A. Pier +18
We report a fully differential study of ionization of the Ne L-shell by Compton scattering of 20 keV photons. We find two physical mechanisms which modify the Compton-electron emis…
