Nuclear quadrupole interaction in glassy Hf1-xCux alloys and their local structures.

Abstract: The electric field gradient (EFG) at Hf sites in amorphous ${\mathrm{Hf}}_{1\mathrm{\ensuremath{-}}\mathrm{x}}$${\mathrm{Cu}}_{\mathrm{x}}$ alloys was measured for x=0.33, 0.44, 0.50, and 0.59 with use of the time-differential perturbed angular correlation technique. The results show no evidence of crystallinelike local order in these alloys, supporting a description of their local structure in terms of a dense random packing of atoms. The local and lattice contributions to the EFG, as well as their dependence on composition, are discussed.

Method and system for applying nqr pulse sequences

Abstract: A method and system for applying nuclear quadrupole resonance (NQR) sequences to a substance and determining presence of a chemical species within the substance using the sequences are described herein. The method includes applying an NQR pulse sequence to the substance using a non-resonant transmitter circuit. The method further includes detecting a NQR signal within the substance and determining presence of a chemical species within the substance using the NQR signal.

121,123sb and 209bi nuclear quadrupole resonance study of complex compounds of antimony(iii) and bismuth(iii) in the temperature range 77-400 k

Abstract: Abstract A large number of solid fluoride and heteroligand acidocomplex compounds of antimony(III) and bismuth(III) with single and mixed cations has been prepared from aqueous solutions. Their crystal structures and 121,123Sb and 209Bi NQR spectra have been investigated in a wide temperature range.
