An overview of both experimental and theoretical results in the field of resonant scattering of
tunable soft and hard x-ray radiation is presented, with a main focus on the closely related …

The authors review the use of core-level resonant photoemission and resonant Auger
spectroscopy to study femtosecond charge-transfer dynamics. Starting from simple models …

Although valence electrons are clearly delocalized in molecular bonding frameworks,
chemists and physicists have long debated the question of whether the core vacancy …

Because of inversion symmetry and particle exchange, all constituents of homonuclear
diatomic molecules are in a quantum mechanically non-local coherent state; this includes …

Polarized oxygen Kα x-ray absorption and emission spectra, near 530 eV, of a single crystal
of Cs 2 UO 2 Cl 4 are reported. With the aid of density functional theory calculations and the …

Double-slit experiments illustrate the quintessential proof for wave–particle complementarity.
If information is missing about which slit the particle has traversed, the particle, behaving as …

Electronic core levels in molecules are highly localized around one atomic site. However, in
single-photon ionization of symmetric molecules, the question of core-hole localization …

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 …

Resonant Auger scattering (RAS) provides information on the core–valence electronic
transition and impresses a rich fingerprint of the electronic structure and nuclear …

Dissociative nuclear motion in core-excited molecular states leads to a splitting of the
fragment Auger lines: the Auger-Doppler effect. We present here for the first time …
