Abstract
For pt.I see ibid., vol.14, p.2457 (1984). The diffuse X-ray scattering from the displacement field around interstitially dissolved N in Nb single crystals was studied at large scattering vectors. For the case of isolated point defects the so-called Stokes-Wilson scattering was observed for the first time. The authors demonstrate that Huang scattering, Stokes-Wilson scattering and the asymmetry of the scattering intensity distribution can be described by the same formalism. From this new description the displacements of the nearest-neighbour Nb atoms and the lattice location of the interstitial N atom are determined.
