Abstract

A very simple method for determining the center (isomer) shift, CS, and the spectral area, A, of a M\"ossbauer spectrum is outlined. Its applicability is demonstrated in two examples viz. pyrite and a ternary sigma-phase Fe-Cr-Ni compound. Sets of the spectra recorded in the temperature interval of 78-295 K for the former, and 78-295 K for the latter were analyzed with the simple and a standard method. CS(T)- and A(T)-data obtained with both ways of the spectra analysis were analyzed in terms of the Debye model. The determined values of the Debye temperatures agree well within the error limit with each other proving that this very simple method is suitable for a quick determining of CS and A spectral parameters.
