Climbing the N-shell resonance ladder of xenon
Steffen Palutke, Michael Martins, Stephan Klumpp +7
The dependency on the excitation energy of ultrafast multi-photon ionization of xenon by intense, short extreme ultraviolet pulses (XUV) was investigated in the vicinity of the 4$d…
Suppression of X-Ray-Induced Radiation Damage to Biomolecules in Aqueous Environments by Immediate Intermolecular Decay of Inner-Shell Vacancies
Andreas Hans, Philipp Schmidt, Catmarna Küstner-Wetekam +13
The predominant reason for the damaging power of high-energy radiation is multiple ionization of a molecule, either direct or via the decay of highly excited intermediates, as e.g.…
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…
Imaging the square of the correlated two-electron wave function of a hydrogen molecule
M. Waitz, R. Y. Bello, D. Metz +21
The toolbox for imaging molecules is well-equipped today. Some techniques visualize the geometrical structure, others the electron density or electron orbitals. Molecules are many-…
Two-particle interference of electron pairs on a molecular level
M. Waitz, D. Metz, J. Lower +19
We investigate the photo-doubleionization of molecules with 400 eV photons. We find that the emitted electrons do not show any sign of two-center interference fringes in thei…
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…
Stepwise contraction of the nf Rydberg shells in the 3d photoionization of multiply-charged xenon ions
S. Schippers, A. Borovik, T. Buhr +8
Triple photoionization of Xe3+, Xe4+ and Xe5+ ions has been studied in the energy range 670-750 eV, including the 3d ionization threshold. The photon-ion merged-beam technique was…
Absolute cross sections for photoionization of Xe ions (1 q 5) at the 3d ionization threshold
S. Schippers, S. Ricz, T. Buhr +26
The photon-ion merged-beams technique has been employed at the new Photon-Ion spectrometer at PETRA III (PIPE) for measuring multiple photoionization of Xe (q=1-5) ions. Tot…
