NUCLEAR DOUBLE-RESONANCE INVESTIGATION OF AG+ SUBSTITUTIONAL IMPURITY IN NACL

Nuclear magnetic double resonance has been used to investigate first-order electric quadrupole interactions of Na23 and Cl35 nuclei near an Ag ion substituted for Na in NaCl. The study has determined the direction of the principal axes, asymmetry parameter, and strength of the interaction e2Qq for sodium ions at a (2, 0, 0) position, and chlorine ions at (2, 1, 0) position relative to the impurity at (0, 0, 0). © 1968 The American Physical Society.
