Mössbauer measurements of one sample of the Pułtusk meteorite were performed at room temperature (300 K) and at temperature of liquid nitrogen (80 K). Following mineralogical phases were identified in Mössbauer spectra: olivine, pyroxene, troilite, kamacite, taenite, and a doublet associated with ferric iron. The differences in the percentage of spectral areas obtained for all subspectra are very small. It means that in the range of these temperatures the Debye–Waller factor is the same for all mineralogical phases present in the investigated sample.
