“…Hence, the xray fluorescence rate, within this model, scales as Z 4 . This is consistent with the rapid increase of the x-ray fluorescence yield with increasing atomic number [67,68]. In Kr, for instance, the first step in the decay cascade of a K hole is dominated by x-ray fluorescence with an x-ray fluorescence yield of about 66%.…”

A basic introduction to the theory underlying x-ray processes is provided. After general remarks on the practical advantages of using x-rays for probing matter, the derivation of the minimal-coupling Hamiltonian within nonrelativistic quantum electrodynamics is outlined. Perturbation theory is reviewed and applied to describe x-ray-induced processes. In connection with x-ray absorption, inner-shell binding energies and the photon energy dependence of the x-ray absorption cross section are discussed. In the context of x-ray scattering, atomic and molecular scattering factors are introduced, the complex index of refraction is derived, and the nonrelativistic theory of Compton scattering is described. The final topic is x-ray fluorescence and Auger decay of inner-shell-excited systems.

“…IAED is, of course, the only Auger process that can take place in an isolated atom. In atoms, this mechanism is well understood: 1,2,3,4,5 The initial core hole is filled by a (valence) electron and the excess energy is transferred via Coulomb interaction to a second (valence) electron, which is emitted subsequently [Fig. 2(a)].…”

“…Since its discovery it has received much attention, because it is a fundamental process yielding deep insights into complex many-body effects in matter. Moreover, the Auger effect has proven to be useful in many experimental situations 2,3,4,5,6 and can be used as an analytical tool. Therefore, an in-depth understanding of the Auger effect is important both for fundamental and practical reasons.…”

Impact of interatomic electronic decay processes on Xe 4d hole decay in the xenon fluorides

A hole in a 4d orbital of atomic xenon relaxes through Auger decay after a lifetime of 3 fs. Adding electronegative fluorine ligands to form xenon fluoride molecules, results in withdrawal of valenceelectron density from Xe. Thus, within the one-center picture of Auger decay, a lowered Xe 4d Auger width would be expected, in contradiction, however, with experiment. Employing extensive ab initio calculations within the framework of many-body Green's functions, we determine all available decay channels in XeFn and characterize these channels by means of a two-hole population analysis. We derive a relation between two-hole population numbers and partial Auger widths. On this basis, interatomic electronic decay processes are demonstrated to be so strong in the xenon fluorides that they overcompensate the reduction in intra-atomic Auger width and lead to the experimentally observed trend. The nature of the relevant processes is discussed. These processes presumably underlie Auger decay in a variety of systems.

“…The X-ray yields per proton for Cu, Ag and Au were calculated by using equation ( 4 smooth six-order curve fitting was done (table 1) on the experimental points of Yield Y(E) from the thick targets using the curve function given in equation ( 7) [3,14,17]. The K, L and M-shell fluorescence yields of the thick samples are listed in table 2 [18,19] and physical properties of Cu, Ag and Au used for the calculation are listed in table 3 [20,21].…”

We conducted a series of fundamental research-based experimentations to measure the X-ray production cross sections of K-, L-, and M-shells from thick samples of Cu, Ag and Au, respectively, for proton beam in a lower energy range of 0.7 - 3.5 MeV utilizing particle induced X-ray emission (PIXE) analysis. The measurement theories based on the Merzbacher-Lewis (ML) relationship and procedure for thick samples are described. The detector efficiency and system calibration were first measured from Fe-55 and Am-241 X-ray sources and the standard sample, respectively. The X-ray yields as a function of the proton energy were measured and fitted for finding the derivatives which were used for the cross section measurement. The obtained results were compared with published data and predictions from the theoretical models of Plane Wave Born Approximation (PWBA) and the advanced ECPSSR. The measured results from Cu were in good agreement with the theoretical predictions, especially in the lower energy regime, and most of the reported data, while for the higher energy regime deviated by a few times but still in the same order of magnitude with the theoretical data. The Ag and Au results were in excellent agreement with published and theoretical values.
