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…
Photoionization of metastable heliumlike C4+(1s 2s 3S1) ions: Precision study of intermediate doubly excited states
A. Müller, E. Lindroth, S. Bari +10
In a joint experimental and theoretical endeavour, photoionization of metastable C4+(1s 2s 3S1) ions via intermediate levels with hollow, double-K-vacancy configurations 2s2p, 2s3p…
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…
Separating Dipole and Quadrupole Contributions to Single-Photon Double Ionization
S. Grundmann, F. Trinter, A. W. Bray +12
We report on a kinematically complete measurement of double ionization of helium by a single 1100 eV circularly polarized photon. By exploiting dipole selection rules in the two-el…
Ultrafast charge redistribution in small iodine containing molecules
Maximilian Hollstein, Karolin Mertens, Nils Gerken +8
The competition between intra molecular charge redistribution and fragmentation has been studied in small molecules containing iodine by using intense ultrashort pulses in the extr…
