| 总结: | Low-temperature nuclear orientation measurements made on-line at the SERC Daresbury Laboratory on142 mEu,141 mSm, and141Pm, with known magnetic dipole moments, have yielded the magnitude of the hyperfine fields of these isotopes in an iron host lattice. Thus measurements for the isotopes139, 138Eu,139 mSm, and138Pm yielded values for the respective magnetic moments. Limits on the thermal relaxation times of Eu and Sm isotopes in Fe were also deduced. The results for138Eu appear to contradict the earlier πh11/2⊗νh11/2 ground-state configuration assignment. © 1992 J.C. Baltzer A.G., Scientific Publishing Company.
