PÓSTERX-ray emission spectra excited by electron incidence from Fe, Ni, Ru, Ag and Te targets were measured with a wavelength dispersive spectrometer. To this purpose, spectra were recorded in a JEOL JXA 8230 microprobe at the Laboratorio de Microscopía Electrónica y Análisis por Rayos X of the Universidad Nacional de Córdoba, Argentina. The atomic transitions studiedinvolve decays to states with vacancies in the L shell. A careful spectral processing was carried out, based on a method of parameter refinement previously implemented. With this method, characteristic energies, relative transition probabilities and natural linewidths, fitted by Voigt profiles, were determined.The origin and shape of the satellite bands appearing at the high energy side of the main lines is also discussed, as well as the Auger radiative structures located at the low energy side of the most intense peaks. Finally, the results obtained are compared with the data available in the literature.
