| Abstract: | Polarized8Li nuclei were produced in a Li3N single crystal by irradiation with polarized neutrons, Β-ray detected NMR signals and spin-lattice relaxation of8Li were observed between B and 300 K. In Li3N there are two non-equivalent Li sites. The corresponding two quadrupole split NMR spectra could be resolved. From the measured relaxation rates activation enthalpies for two diffusion processes were deduced. |
