Multiple photodetachment of carbon anions via single and double core-hole creation
A. Perry-Sassmannshausen, T. Buhr, A. Borovik +8
We report on new measurements of m-fold photodetachment (m=2-5) of carbon anions via K-shell excitation and ionization. The experiments were carried out employing the photon-ion me…
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 single, double, and triple photoionization of C+ ions
A. Müller, A. Borovik, T. Buhr +8
Single, double, and triple ionization of the C+ ion by a single photon have been investigated in the energy range 286 to 326 eV around the K-shell single-ionization threshold at an…
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…
Prominent role of multi-electron processes in K-shell double and triple photodetachment of oxygen anions
S. Schippers, R. Beerwerth, L. Abrok +7
The photon-ion merged-beams technique was used at a synchrotron light source for measuring absolute cross sections of double and triple photodetachment of O ions. The experim…
Experimental investigation of left-right asymmetry in photon-atom interaction
S. Ricz, T. Buhr, Á. Kövér +5
Single ionization of noble gas atoms by linearly polarized synchrotron radiation has been studied by employing angle- and energy-resolved photoelectron spectroscopy. The measuremen…
Stepwise contraction of the nf Rydberg shells in the 3d photoionization of multiply-charged xenon ions
