The recent development of experimental photoionization cross sections of atomic ions has
been reviewed. Owing to the construction of intense undulator-based photon sources it has …

This article reviews the current status of inner-shell spectroscopies of free atoms and
molecules using high-resolution soft-x-ray monochromators installed in the soft-x-ray …

Absolute measurements of cross sections for photoionization of a statistical admixture of
Ne+ in the 2 P 3/2 o ground state and the 2 P 1/2 o metastable state are reported in the …

This review covers the outer core level photoionization of the free 3d metal atoms from Sc to
Cu. The experimental 3p, 3s and 2p photoemission and photoabsorption spectra are …

Short wavelength free-electron lasers (FELs), providing pulses of ultrahigh photon intensity,
have revolutionized spectroscopy on ionic targets. Their exceptional photon flux enables …

The online atomic database of NORAD-Atomic-Data, where NORAD stands for Nahar OSU
Radiative, is part of the data sources of the two international collaborations of the Opacity …

An experimental K-shell photodetachment study of Li− giving rise to doubly photoionized Li+
ions has been carried out at the Advanced Light Source, using a collinear photon-ion beam …

We have investigated photoionization (PI) of the 1 S ground state and 3 P o metastable
states of C 2+ ions in the photon energy range 40.8-56.9 eV at a resolution of 30 meV …

K-shell photodetachment from C− has been investigated in the photon energy range
between 280 and 285 eV using the merged ion-beam–photon-beam technique. C− ions …

Absolute cross sections for the K-shell photoionization of ground-state Li-like carbon [C
3+(1s 2 2s 2 S)] ions were measured by employing the ion–photon merged-beams …
