Abstract:Absorption Mössbauer spectra were measured on low temperature (6–21 mK) oriented nuclei. For magnetic orientation this method allows the determination of the sign of the parent state magnetic moment. The method enables the determination of the parent state quadrupole coupling even for a polycrystalline sample. Signs of ground state magnetic moments for191Pt and193Os, and electric quadrupole moments for125Tem and129Te are determined.
