Description	The conversion electrons emitted with initial energy of 7.3 keV from the K-shell of 57 Fe atoms were measured with an electrostatic spectrometer set to the instrumental resolution of 7 eV. The source - Co-57 on an Al backing - was covered in successive steps by six evaporated Au layers and changes of the line shapes were recorded. The thicknesses of the Au absorbers determined by neutron activation analysis varied from 2.7 to 21 nm, i.e. up to about three times the inelastic mean free path of the 7.3 keV electrons. The individual elastic and inelastic scattering events in the A1 backing, Au absorbers and carbonaceous contamination overlayer were simulated by the Monte Carlo method. When the Au energy loss function derived by Yoshikawa et al. was applied in MC simulations, a reasonable agreement with measured line shapes was reached even for the thickest Au absorbers.
