Near L-Edge Single and Multiple Photoionization of Doubly Charged Iron Ions
Stefan Schippers, Randolf Beerwerth, Sadia Bari +11
Using the photon-ion merged-beams technique at a synchrotron light source, we have measured relative cross sections for single and up to five-fold photoionization of Fe ions…
Near L-edge photoionization of triply charged iron ions
Randolf Beerwerth, Ticia Buhr, Alexander Perry-Saßmannshausen +12
Relative cross sections for -fold photoionization () of Fe by single photon absorption were measured employing the photon-ion merged-beams setup PIPE at the…
QED radiative corrections to the P-P fine-structure in fluorinelike ions
A. V. Volotka, M. Bilal, R. Beerwerth +3
Ab initio calculations of QED radiative corrections to the - fine-structure transition energy are performed for selected F-like ions. These calculations are…
High-precision calculations of the spin-allowed transition in C {\small III}
Moazzam Bilal, Andrey V Volotka, Randolf Beerwerth +3
Large-scale relativistic calculations are performed for the transition energy and line strength of the transition in Be-like…
The photon-ion merged-beams experiment PIPE at PETRAIII - The first five years
S. Schippers, T. Buhr, A. Borovik +13
The Photon-Ion Spectrometer at PETRA III - in short, PIPE - is a permanently installed user facility at the "Variable Polarization XUV Beamline" P04 of the synchrotron light source…
Line strengths of QED-sensitive forbidden transitions in B-, Al-, F- and Cl-like ions
Moazzam Bilal, Andrey V Volotka, Randolf Beerwerth +1
The magnetic dipole (M1) line strength between the fine-structure levels of the ground configurations in B-, F-, Al- and Cl-like ions are calculated for the four elements argon, ir…
