Jk. Jung et al., IMPURITY EFFECT ON N-14 NQR IN A MIXED SYSTEM [(CH2)(6)N-4](1-X)[KNO2](X), Journal of the Korean Physical Society, 29, 1996, pp. 547-550
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.
