Abstract
For Pt.I see abstr. A12758 of 1972. The diffuse scattering of long wavelength (7-8AA) neutrons by fluorite solid solutions of YF3 in CaF2 in the composition range Ca(Y)F2.1 to Ca(Y)F2.32 has been studied. The local distribution of defects is revealed by the variation of scattering with sin theta / lambda . Earlier inferences (part I) from the Bragg neutron diffraction measurements on the clustering of the two types of fluoride interstitial in this system are supported by the present results.
