Analysis of Complex Mössbauer Spectra by Stripping Techniques

  • Arthur H. MuirJr.

Abstract

The increasing activity in Mössbauer effect research has resnite the publication and analysis of Mössbauer spectra of several hunderd different substances, and this new field of spectroscopy is beginning to be used as a standard analytical tool, Quantitative analysis in the presence of several phases, some of which may have overlapping lines, presents a number of problems. A method of analysis involving, compurerbased spectrum stripping is described, and examp pplications are discussed. A family of computer programs processes Mössbauer spectra for use as unknowns and reference standards and performs the stripping calculations. Reference spectra can be either least-squares-fit Lorentzian representations or tabulated functions (spectra not suitable for fitting) Appropriate amounts of any number of reference spectra are subtracted from the unknowns with the amounts being varied interatively until the residuals become satisfactorily small. This approach has been particularly useful in analyzing certain meteorite spectra, where as many as six distinct iron-containing phases have been observed.
