Özet
Nuclear quadrupole resonance (NQR) with use of pulses of low magnetic field has been studied. The technique is based on the matching of proton frequency (nu(L)) to one of the NQR frequencies (nu(0), nu(+) or nu(-)) for the period of application of pulse magnetic field. Theoretical approach to analyse the NQR experiments in pulse magnetic fields is outlined. In this work the NQR on ammonium nitrate (AN) sample for specific case of nu(L) = nu(0) have been studied. It has been shown that the technique provides essential shortening the effective spin-lattice relaxation time and can be applied for the detection of explosive materials.
