metadata.name: dc.description.abstract
metadata.value: The sensitivity of technique of nuclear quadrupole resonance (NQR) in measuring of the echo
  signals of ore, containing chalcopyrite CuFeS2, was investigated. It is shown that the quadrupole
  echo signals are observed until the sample occupies no less than 10% of the total volume of
  the solenoidal coil sensor of NQR spectrometer. Industrially manufactured NQR spectrometer
  Redstone with the standard sensor was used. It is shown that further reduction of the volume
  of the sample leads to signal/noise ratio is less than 1 and the observation is only possible with
  a multiple increase of the number of savings. Refs 18. Figs 4.
