Neutron Scattering from Solids

The use of neutron diffraction in establishing details of solid structures has developed as a complement to X-ray diffraction for specialized and restricted applications. Stated very simply, one can say that neutron methods should never be considered because of expense and intensity considerations if X rays can possibly do the job. It is only for those cases where the use of neutron radiation offers additional or unique information that the power of the neutron technique becomes significant. Some of the advantages and the limitations of th method are outlined in the following discussion.

Rush (1967) measured the inelastic incoherent neutron scattering from solid benzene and determined the phonon frequency distribution. Nakamura and Miyazawa (1969) carried out a complete Brillouin zone lattice dynamics calculation using the potential constants of Harada and Shimanouchi (1967), assuming the benzene molecule to be a nonvibrating rigid body. These authors first obtained agreement to better than 6% with Harada and Shimanouchi for the q = 0 modes. They then calculated the frequency distribution and were able to fit the experimental specific heat to better than 2 % by taking into account the internal modes as well and...

The polymer concentration profile has been measured by small-angle neutron scattering from polymers adsorbed onto colloidal particles [70,71] or porous media [72] and from flat surfaces with neutron reflectivity [73] and optical reflectometry [74]. The fraction of segments bound to the solid surface is nicely revealed in NMR studies [75], infrared spectroscopy [76], and electron spin resonance [77]. An example of the concentration profile obtained by inverting neutron scattering measurements appears in Fig. XI-7, showing a typical surface volume fraction of 0.25 and layer thickness of 10-15 nm. The profile decays rapidly and monotonically but does not exhibit power-law scaling [70].
