Abstract

The recoilless absorption spectra of the 103-keV $γ$ rays from ${Eu}^{153 m}$ in ${Eu}^{153}$ situated in europium oxide and in europium iron garnet were measured at 20°K. The source used was ${Sm}^{153}$ in the form of an oxide at 20°K. With the ${Eu}_{2}$ $O_{3}$ absorber an unsplit absorption line with (2.1±0.4) mm/sec width at half-maximum was obtained. From the hyperfine Zeeman splittings obtained with the europium iron garnet absorber, a value of (+2.01±0.09) nm. was found for the magnetic moment of the 103-keV level of the ${Eu}^{153}$ . This value is in very good agreement with the predictions of the unified model.
