Local hyperfine interactions on Fe nuclei in UFe5Sn compound were determined in Mössbauer experiment. The analysis of the Mössbauer spectra measured at room temperature reveals the presence of two doublets only. Absorption line width indicates that neither distribution of quadrupole splitting nor isomer shift exists in the alloy. The measurements at 13 K show the presence of four magnetic components. Because the magnetic dipole and electric quadrupole interactions are present, full Hamiltonian was used to determine the hyperfine interactions for each iron site. Electric field gradient determined at low temperatures agrees with quadrupole splitting observed at room temperature. Absorption areas of the components at low and at high temperatures correspond well to the occupation of
