Interference phenomena in nuclear quadrupole scattering of Mössbauer γ-radiation☆

Abstract The purely nuclear quadrupole maxima have been observed in diffraction of resonant 14.4 keV γ-quanta by a Fe 3 BO 6 single crystal. Mossbauer spectra of quadrupole reflections (11, 2, 0) and (710) have been measured and the relationship between the shape of these spectra and the details of the structure composed by electric field gradients at Fe nuclei have been established.
