CHEBYSHEV APPROXIMATIONS FOR AN INHOMOGENEOUSLY BROADENED LINE-SHAPE IN MOSSBAUER-SPECTROSCOPY

We present the analysis of an inhomogeneously broadened Mossbauer line -shape, from which we obtained a power series expansion, that includes the absorber thickness (T-a) and the interference effects (xi(0)) At the same time, we give the al ea and depth dependency formulae as func tion of the T-a and xi(0) parameters. A new line-shape is built as a l ineal combination of the traditional transmission integral (TI) with t he inhomogeneously broadened line-shape, which is useful for absorbers that have a partial or total inhomogeneous broadening. Finally, a com parative analysis of the obtained results for the potassium ferrocyani de compound and the stainless steel foil is carried out using the new line-shape with respect to the TI to show its reliability.
