IMPURITY EFFECT ON N-14 NQR IN A MIXED SYSTEM [(CH2)(6)N-4](1-X)[KNO2](X)

The x-ray diffraction and N-14 nuclear quadrupole resonance of the mix ed system [(CH2)(6) N-4](1-x) [KNO2](x) for the range of 0 less than o r equal to x less than or equal to 0.41 have been investigated at room temperature. The x-ray diffraction patterns for the system show that mixing KNO2 into (CH2)(6)N-4 leads to a formation of KNO2 clusters in the cubic phase of (CH2)(6) N-4. The measurement of N-14 NQR shows tha t KNO2 does not cause any ordered change in the configuration of elect ric field gradient (EFG) at the N-14 Site in the (CH2)(6)N-4 matrix. T he rates of broadening and intensity loss of N-14 NQR line with increa sing x in [(CH2)(6)N-4](1-x) [KNO2](x) are found to be weaker than tho se in Na-1-x Ag-x NO2 recently reported.
