The ability to perform attosecond-pump attosecond-probe spectroscopy (APAPS) is a
longstanding goal in ultrafast science. While first pioneering experiments demonstrated the …

We report calculations of accurate high lying resonance energies of the [3 s 3 2 p (D 5/2° 2)
3] nd and [3 s 3 2 p (P 3/2° 2) 3] nd Rydberg series originating from the ground 3 s 3 2 p 4 P …

Multiple ionization of the Ar+(3 s 2 3 p 5) ion by a single photon has been investigated in the
photon-energy range 250–1800 eV employing the photon-ion merged-beams technique …

Calculations of high-lying energy resonances of 12 Rydberg series due to the 4 p→ nd and
4 p→ ns transitions from the 4 s 24 p 3 3 S° 3/2 ground-state and the 4 s 24 p 3 2 P° 3/2, 1/2 …

It is a pleasure to announce that after the installation of the IBM Blue Gene/P at NIC/JSC in
May 2009, as part of the Gauss Centre for Supercomputing (GCS)–linking together the three …

Absolute cross sections for the K-shell photoionization of Be-like and Li-like atomic nitrogen
ions were measured by employing the ion–photon merged-beam technique at the SOLEIL …

Absolute single-photoionization cross-section measurements for Se 2+ ions were performed
at the Advanced Light Source at Lawrence Berkeley National Laboratory using the merged …

We report on experimental and theoretical results for the photoionization of Ag-like xenon
ions, Xe 7+, in the photon energy range 95–145 eV. The measurements were carried out at …

We employ the R matrix with time dependence method to investigate extreme-ultraviolet-
initiated high-order harmonic generation (XIHHG) in Ar+. Using a combination of extreme …

A kinematically complete experiment on two-photon double ionization of Ar by free-electron
laser radiation with a photon energy of 27.93 eV was performed. The electron energy …
