Application of a linear combination of the Lorentzian function and its square has led to better description of Mossbauer spectra obtained using a resonance detector, compared with description using a simple Lorentzian. Mathematical fitting and descri

We propose a mathematical description of the refined shape of absorption lines in Mossbauer spectra obtained using a resonant detector, taking into account distortions in the lineshape as a result of the influence of factors introduced by the experim
