NUCLEAR MAGNETIC RESONANCE STUDIES OF NEUTRON-IRRADIATED ALKALI HALIDES

· Phys. and Chem. Solids
Nuclear magnetic resonance techniques were used to investigate radiation damage in some alkali halides. The resonances of Li/sup 7/, Na/sup 23/, Br/sup 81/, and I/sup 127/, were studied to determine the concentration and arrangement of defects in neutron-irradiated single crystals of NaI, LiI, KI, and KBr. A method of analysis was developed, based on changes of line shape due to defect- induced quadrupolar effects. The experimental results are in fairly good agreement with theoretical predictions based, principally, on the methods of Witz and Koehler and of Brinkman. Information was obtained on the strength of screening in coulomb potentials for atom-atom collisions and on the deformation of ion cores by charges external to the ions. Evidence for orientation of dislocations in preferred directions was noted in crystals of NaI and KI. (auth)
