This software allows a complex treatment of Mössbauer spectra starting from a setting of the background and of the individual components by the mouse drag-and-drop technique. It is designed for the spectroscopy of 57Fe and 119Sn isotopes. An original method has been applied combining a non-linear least-squares procedure with the Fast Fourier Transform technique. Improved matrix formalism allows all imaginable physical models of Mössbauer spectra. It is possible to introduce both hyperfine magnetic field and quadrupole splitting distribution. For the final thickness of the sample the transmission integral calculation can be established. A special parameter can be introduced that characterises the increase in the width of all spectra lines in dependence on their distance from the spectrum middle (on the absolute velocity). The fitted spectra can be taken in the transmission or back-scattering (conversion electrons) geometry. The fitting process is very fast also for complicated spectra.
