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…
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…
Near--K-edge double and triple detachment of the F- negative ion: observation of direct two-electron ejection by a single photon
A. Müller, A. Borovik, S. Bari +9
Double and triple detachment of the F-(1s2 2s2 2p6) negative ion by a single photon have been investigated in the photon energy range 660 to 1000 eV. The experimental data provide…
