A careful inspection on the tin L x-ray spectrum induced by electron impact was carried out, with the aim of obtaining fundamental atomic properties related to core ionizations and subsequent emissions. A bulk tin standard was irradiated, the resulting spectrum being recorded with a commercial wavelength dispersive spectrometer, and processed by means of a parameter optimization method previously developed. Characteristic energies, relative transition probabilities and natural linewidths were therefore experimentally determined for this element, and compared with data from the literature, when available. Satellite and radiative Auger effect structures were also investigated, for which the corresponding energy shifts and relative intensities were obtained. A number of these parameters were determined, even in overlapping peaks and weak transitions, which evidences the robustness of the spectral processing method used.
