“…A combination of energy shifts and line broadening was used by Banas et al 416 to study solid state effects in L-O X-ray transitions induced by O, S and Si. Kb, La and Lb emissions from Mo were studied by Acharya et al 417 to see the effect of V 2 O 5 incorporation in a MoO 3 matrix.…”

The review also covers a survey of applications, including sample preparation, geological, environmental, archaeological, forensic, biological, clinical, thin films, chemical state and speciation studies. During the current review period, publications have demonstrated the development of sub-100 nm X-ray beams for SR microprobe analysis together with the wider use of WD spectrometers in this application. There is evidence of an extension of the application of XRF as a reference technique, with XRF increasingly being used in modern laboratories in place of older wet-chemical methods, and computer-modelling studies continue to be popular in extending the understanding of various XRF phenomena. Some interesting work has been undertaken in the measurement of radiative Auger effects using high-resolution WDXRF instruments. However, the potential for future developments in XRF is illustrated by research into ultra-high resolution microcalorimeter detector devices, which are still at the experimental stage and have not yet progressed to the status of useful practical devices.

H⁺ and He^2 + induced W L X‐rays intensity ratios: part I, Si(Li) data and EDS high resolution insight

Recently, the authors have presented experimental evidences that for some energy windows, proton-induced W L shell X-rays intensity ratios of transitions to L 1 subshell depend on the ion beam energy and on the chemical species even after known matrix effects are subtracted. These results, which put in question the assumption of the invariance of the relative intensity of X-ray transitions to the same atomic subshells, are further exploited in this work, where more data for three different W compounds (W, Li 2 WO 4 and P 2 O 5 .24WO 3 .xH 2 O) are presented followed by a detailed study using an ultra-pure (99.995%) W thick foil, used to avoid any possible target contamination interference on the results. Samples were irradiated by H + beams in various conditions in the energy range between 0.25 and 2.38 MeV and by He 2 + beams having energies between 3.5 and 5.0 MeV. Spectra were collected using the Si(Li) detector at CTN 2.5 MV Van de Graaff standard Proton-Induced X-ray Emission (PIXE) set-up as well as using the Energy Dispersive Spectrometry (EDS) high resolution X-ray microcalorimeter spectrometer (XMS) at CTN 3.0 MV Tandetron accelerator high resolution high energy (HRHE) PIXE end station. Results were normalized to the theoretical intensity ratios and plotted as function of the ratio of collision characteristic times allowing the comparison of H + and He 2 + results. W L X-rays intensity ratio variations are presented and compared with theoretical expected results. Radiative Auger emission transitions observed in an EDS high resolution XMS spectra are shown to probably play a crucial role in the highly unexpected results obtained for intensity ratios of transitions to the same subshell.
