“…The energy E 0 of the incident electrons has been chosen to be higher than the threshold of the studied emission: in the present case 1560 and 850 eV for the Al 1s and Ni 2p 3/2 binding energies respectively. Following the ionization of the atoms present in the sample, characteristic x-rays are emitted [28,29]. They are dispersed by a high-resolution (10-10) quartz (for Al K emission) or (10-10) beryl (for Ni L emission) bent crystal and detected in a gas-flux counter working in the Geiger regime.…”

“…These equations are suitable for a full description of resonant, non-resonant and off-resonant scattering processes in matter. Tulkki and Åberg considered off-resonant X-ray scattering ( y 1 E i − C i ) within the dipole approximation (exp(ık • r) ≈ 1). In this picture, the off-resonant scattering process may be described as an excitation of the initial core electron into an intermediate virtual state.…”

“…One of them, X-ray spectroscopy, is focused on examining the energy distribution of inner-and outer-shell atomic electrons quantum states in different conditions [1]. The study of the interaction of X-ray radiation with atoms allows determining the electronic structure of matter as well as investigating the intra/inter-atomic and intra/inter-molecular electronic processes.…”

We review the high energy resolution off-resonant spectroscopy (HEROS) technique. HEROS probes the unoccupied electronic states of matter in a single-shot manner thanks to the combination of off-resonant excitation around atomic core states using wavelength dispersive X-ray detection setups. In this review we provide a general introduction to the field of X-ray spectroscopy together with the specification of the available X-ray techniques and X-ray methodologies. Next, the theoretical description of the HEROS approach is introduced with a special focus on the derivation of the X-ray emission and X-ray absorption correspondence relation at off-resonant excitation conditions. Finally, a number of experimental HEROS reports are reviewed in the field of chemistry and material science. We emphasize the applicability of HEROS to pulsed X-ray sources, like X-ray free electron lasers, and support the review with experimental examples. The review is complemented with perspectives on and possible further applications of the HEROS technique to the field of X-ray science.

“…The electron beam comes from a Pierce gun. Following the ionization of the atoms present in the sample, characteristic x-rays were emitted [29,30], then dispersed by a (100) bent beryl crystal. The radiation was detected in a gas-flux counter working in the Geiger regime.…”

We present the results of the characterization of Mg/Co periodic multilayers and their thermal stability for the EUV range. The annealing study is performed up to a temperature of 400°C. Images obtained by scanning transmission electron microscopy and electron energy loss spectroscopy clearly show the good quality of the multilayer structure. The measurements of the EUV reflectivity around 25 nm (~49 eV) indicate that the reflectivity decreases when the annealing temperature increases above 300°C. X-ray emission spectroscopy is performed to determine the chemical state of the Mg atoms within the Mg/Co multilayer. Nuclear magnetic resonance used to determine the chemical state of the Co atoms and scanning electron microscopy images of cross sections of the Mg/Co multilayers reveal changes in the morphology of the stack from an annealing temperature of 305°C. This explains the observed reflectivity loss.
