Abstract

Abstract The criteria for the selection of materials for mounting absorbers include their mechanical and chemical properties and their attenuation of the γ-rays and X-rays emitted from the Mössbauer source. Attenuation of the 14.4-keV γ-ray and 6.3-keV X-ray associated with 57Fe was measured for nine commercial materials including plastics and metals. The linear absorption coefficients and half-thicknesses for each material were measured. The usefulness and limitations of each material are discussed, along with three different absorber mounting techniques.
