Opis:: Factors determining the Auger signal intensity are discussed. It is indicated that using standards is the only reasonable way for quantitative Auger analysis (QAA). Approaches to QAA without and with matrix corrections are presented. It is shown that the matrix correction connected with atomic concentrations of pure standards is the most important and that the other matrix corrections (e.g. those connected with the attenuation length and backscattering factor) do not improve appreciably the QAA exactness in many examples taken from the literature. The examples indicate that in the case of metallic alloys the properly performed QAA gives the relative atomic concentrations with the error not exceeding few percent.

Opis:: The angular distributions of secondary electrons (including Auger electrons) of different energies emitted from polycrystalline silver bombarded with primary electrons (E$\text{}_{p}$ = 1000 and 2500 eV) were measured with a RFA analyzer equipped with an additional collector (acceptance angle ≈ 4°). Additionally, the angular distributions of primary electrons of different energies elastically backscattered from the same sample were also investigated by means of a specially constructed rotable RFA analyzer equipped with a channeltron. The results obtained show the cosine distribution of secondary and Auger electrons emitted as shown previously in the literature. The angular distributions of electrons backscattered elastically depend on electron energy and are in good agreement with theoretical calculations (Monte Carlo simulation of primary electrons trajectories in solids) proposed by Jabłoński.

Opis:: The experimental values of Inelastic Mean Free Path (λ$\text{}_{IMFP}$) of electrons in noble metals (Ag, Au, Cu) are determined in the electron energy range 150-2000 eV. The method used consists of the measurements and theoretical calculations of the coefficient of elastic backscattering of electrons from a solid surface η$\text{}_{e}$. The obtained values of λ$\text{}_{IMFP}$ are compared with the data available in the literature.
