“…The emitting intensity distribution of KL n satellites I n KL , i.e. Kα satellite lines due to multiple L-shell vacancies, usually follows the binomial law [32] I n KL ∼ C 8 n P n L (1 − P L ) 8−n where P L is the ionization probability of removing one arbitrary L electron from the L-shell, n is the number of vacancies formed in this shell and C 8 n is the binomial coefficient. From the intensities of the satellite lines, it is possible to deduce the population of L vacancies at the time of K x-ray transition if the fluorescence yield for each satellite line is available.…”

Photon-induced K x-ray spectra of Ca, Ti, Fe, Zn and Ge have been investigated. The measurements have been made using a crystal spectrometer combined with a thin scintillation detector. Excited by the collimated photon beam from an Rh-anode x-ray tube, the spectra of all these elements reveal the existence of radiative Auger emission (RAE) structure and the satellite and hypersatellite lines along with the diagram lines. The energies and intensities of the Kα 2 , Kα 1 , Kβ 1,3 and Kβ 5 diagram lines and the Kα satellites and hypersatellite transitions are presented. The intensity of the RAE structure corresponding to the Kβ 1,3 x-ray transition and the energy of the RAE edge for each element is also reported. The measured results have been compared with the values from other sources such as electron/heavy-ion excitation and theoretical values. From the intensities of the satellite lines of these elements, the average L-vacancy fraction P L has been deduced in each case.

“…x values with the increase of average valence electron density for several aluminium, silicon, sulphur and chlorine compounds, 16,61 supported by additional measurements on gaseous samples, 46 further revealed the importance of chemical bonding in the transfer of vacancies from valence levels of ligand atoms. In atoms with lower effective charges, valence electrons are more bound to the central atom.…”

“…First, it should be recalled that pioneering work on relating the electron rearrangement to chemical bonding properties was done in the 1970s, e.g. [21,84]. It was observed that the average L-shell ionization probability at the moment of x-ray emission p * L decreases with increasing average total valence-electron density D v (number of valence electrons/Å 3 ) of a compound [26].…”

We report on the study of heavy-ion-induced Si KL x-ray satellite spectra of several 3d, 4d and 5d silicides, with the aim of elucidating the trends in bonding properties of transition metal (TM) silicides. Measurements of the 43 MeV Ne 3+ -beam-induced Si KL spectra of elemental silicon and compound targets were performed at the Paul Scherrer Institute, Villigen, Switzerland, with a high-resolution von Hamos crystal spectrometer. The interpretation of the data was based on the importance of the effect of the solid and chemical environment on the KL x-ray satellite relative intensities due to the L-vacancy refilling by intra-and inter-atomic electron transitions. Within the framework of a statistical procedure for L-shell vacancy refilling the average L-shell rearrangement probability for each silicide was extracted so that calculated x-ray intensity distributions matched the experimental ones. The results are discussed in terms of the interplay of Si-Si, Si-TM and TM-TM bonding interactions in the studied TM silicides.
