Abstract: Electron interaction parameters of 16 standard inorganic salts of d-block elements are determined by measuring their mass stopping power by recording the spectrum of electrons incident on and transmitted by them.  137Cs and 207Bi internal conversion sources are used as the source of 614 keV and 942 keV internal conversion electrons and Si (Li) detector coupled to an 8K multichannel analyzer as the spectrometer to record these spectra.  The effective atomic number of these salts for 614 keV and 942 keV electron interactions are determined by substituting their measured mass stopping power in the semi empirical relation between the mass stopping power and atomic number. This semi empirical formula is arrived at by plotting and fitting the measured mass stopping power of Al, Cu, Ag, Sn, Au and Pb against their atomic number. The experimental results are compared with the theoretical values of effective atomic number for electron and photon interaction for organic and inorganic samples. It is observed that effective atomic number of inorganic salts is the same for both electron and photon interactions in the energy range of current study. Stopping cross section is derived from mass stopping power and effective electron density from the effective atomic number and their dependence on effective atomic number are studied.
