The photon-ion merged-beams technique for the photoionisation of mass/charge selected
ionised atoms, molecules and clusters by x-rays from synchrotron radiation sources is …

Auger electrons can be highly radiotoxic when they are used to irradiate specific molecular
sites. This has spurred basic science investigations of their radiobiological effects and …

We present an ab initio computational study of the Auger electron spectrum of benzene.
Auger electron spectroscopy exploits the Auger–Meitner effect, and although it is …

We publish three Roadmaps on photonic, electronic and atomic collision physics in order to
celebrate the 60th anniversary of the ICPEAC conference. In Roadmap I, we focus on the …

The photoionization-excitation spectrum of Ne i, in which an electron in the 1 s shell is
ionized and the 2 p orbital electron simultaneously excited to the np orbital, is investigated in …

The emission of an Auger electron is the predominant relaxation mechanism of core-vacant
states in molecules composed of light nuclei. In this non-radiative decay process, one …

In this study, a detailed calibration of the performance of modern ab initio wave function
methods in the domain of X-ray absorption spectroscopy (XAS) is presented. It has been …

In a joint experimental and theoretical endeavor, photoionization of metastable C 4+(1 s 2 s
S 1 3) ions via intermediate levels with hollow, double-K-vacancy configurations 2 s 2 p, 2 s …

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

Ion yields following X-ray absorption of the cationic series NHy+ (y= 0–3) were measured to
identify the characteristic absorption resonances in the energy range of the atomic nitrogen …
