Abstract
Cross-processes of neutron activated, polarized nuclei I with surrounding stable host nuclei S are observed in diverse solids, using an in-beam NMR technique where the polarized I nuclei are produced by capture of polarized thermal neutrons. The polarization is determined by measuring the 0°-180° asymmetry of the β-decay radiation of these nuclei. The following cross-processes are studied:8Li-6Li innatLi metal;8Li-7Li in7Li metal;8Li-6Li innatLiF (single crystal);8Li-93Nb in7LiNbO3 (single crystal);20F-19F in MgF2 (single crystal). Two applications are presented: a) Determination of the temperature dependence of the electrical quadrupole coupling constant of93Nb in LiNbO3; b) Observation of radiation induced point defects in MgF2 and their thermal annealing. All measurements are performed without any radiofrequency irradiation.
