Abstract

Abstract Mössbauer absorption of Fe 57 in naturally occuring and synthetic crystals of FeS 2, marcasite, has been studied in the ideal absorber thickness in the transmission geometry from a Co 57/Rh and Co 57/LiNbO 3 source. The recoilles fraction at room temperature, 298 K, has been obtained to be 0.2 and the mean square displacement < r 2 > was found to be 13×10 -19 cm 2 at room temperature, 298 K. Because of the small size of marcasite crystals it has not been possible to record good spectra of the monocrystals as a function of the orientation of the incident gamma rays from Co 57/LiNbO 3 source.
