NA-23 NMR AND N-14 NQR IN MIXED-CRYSTALS NA1-XAGXNO2

The Na-23 (I = 3/2) NMR powder pattern for the m = 1/2 <-> m = -1/2 tr ansition, broadened by the second-order quadrupole interaction, was in vestigated in mixed crystals Na1-xAgxNO2 (x less than or equal to 0.16 ). From the intensity loss of the Na-23 NMR line caused by the Ag+-imp urity, the range of the quadrupole interaction in the Na-23 NMR centra l line was estimated. The range comprises ionic charges approximately up to the first nearest neighbour Na+ site from the Na-23 nucleus, sho wing a large difference compared with that obtained from the N-14 NQR investigation in the same system.
