We review recent work on the photoionization of atomic ions of astrophysical interest that
has been carried out at the photon-ion merged-beams setup PIPE, a permanently installed …

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 …

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 …

The negative ion of cerium is investigated experimentally with tunable infrared laser
photodetachment spectroscopy and theoretically with relativistic configuration interaction in …

The negative ion of cerium is investigated using tunable laser photodetachment threshold
spectroscopy. The relative cross section for photodetachment from Ce− is measured over …

With emphasis on K-shell ionization and K-shell excitation mediated by the absorption of a
single photon the present paper provides an overview of the status of experiments in which …

This work is an ab initio study of the 2 p 3 4 S 3/2 o, and 2 D 3/2, 5/2 o states of C-and 2 p 2 3
P 0, 1, 2, 1 D 2, and 1 S 0 states of neutral carbon. We use the multiconfiguration Hartree …

The photon-ion merged-beam technique was used at a synchrotron light source for
measuring the absolute cross sections of the double and triple photodetachment of O− ions …

Experimental cross sections for m-fold photodetachment (m= 3–6) of silicon anions via K-
shell excitation and ionization were measured in the photon-energy range of 1830–1900 eV …

Single and double ionization of berylliumlike C 2+ by a single photon is investigated in the
energy range from 292 to 350 eV in the vicinity of the K-shell single-ionization threshold …
