A rather complete understanding is emerging of the process of full fragmentation of the
helium atom following absorption of a single photon. In this review the major experimental …

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 …

An experimental and theoretical study of the electronic structure of copper phthalocyanine
(CuPc) molecule is presented. We performed x-ray photoemission spectroscopy (XPS) and …

The exposure of molecules to attosecond extreme-ultraviolet (XUV) pulses offers a unique
opportunity to study the early stages of coupled electron–nuclear dynamics in which the role …

The linewidths of a series of core excited atoms and small molecules have been measured
in photoabsorption with ultra high resolution. The widths of transitions to the antibonding π …

The study of the emission of two electrons from an atom by absorption of a single energetic
photon has become of much current interest because it provides the most detailed …

By exciting a series of 1 s 2 S 0 1→ 1 snp P 1 1 transitions in heliumlike nitrogen ions with
linearly polarized monochromatic soft x rays at the Elettra facility, we found a change in the …

High-resolution carbon K-edge X-ray photoelectron, X-ray absorption, non-resonant and
resonant Auger spectra are presented of gas phase trans-1, 3-butadiene alongside a …

Helium nanodroplets are ideal model systems to unravel the complex interaction of
condensed matter with ionizing radiation. Here we study the effect of purely elastic electron …

We report a joint experimental and theoretical study of circular dichroism in the valence
photoelectron spectra of a free chiral molecule. The circular dichroism in photoelectron …
