Abstract

| A single-crystal ENDOR study of S-2(-), Se-2(-) and SSe- defects in NaCl is presented. ENDOR signals corresponding with interactions with the nearest neighbouring Na+ ions are found. For each interaction, the superhyperfine (SHF) and nuclear quadrupole coupling tensors are determined. These ENDOR results can be explained only by assuming a monovacancy model, i.e, the S-2(-), Se-2(-) or SSe- ion replaces a single Cl- ion on a lattice site. Analysis of the ENDOR data also reveals that the nearest neighbouring Na+ ions are displaced with respect to their lattice position. The size of the defect ions suggests that they will be incorporated into the NaCl lattice under great strain. |
