Focus of this volume is on scientific applications but issues of instrumental availabilities and methods of data processing are also covered to help scientists from such diverse fields as crystallography, mineral physics, geochemistry, rock mechanics, materials science, biomineralogy become familiar with neutron scattering. A few years ago European mineralogists spearheaded a similar initiative that resulted in a special issue of the European Journal of Mineralogy Volume 14, Since then the field has much advanced and a review volume that is widely available is highly desirable.
At present there is really no easy access for earth scientists to this field and a more focused treatise can complement Bacon's book, now in its third edition, which is still a classic. The purpose of this volume is to provide an introduction for those not yet familiar with neutrons by describing basic features of neutrons and their interaction with matter as well illustrating important applications. The volume is divided into 17 Chapters.
The first two chapters introduce properties of neutrons and neutron facilities, setting the stage for applications. Some applications rely on single crystals Chapter 3 but mostly powders Chapters and bulk polycrystals Chapters are analyzed, at ambient conditions as well as low and high temperature and high pressure Chapters Characterization of magnetic structures remains a core application of neutron scattering Chapter 6. The analysis of neutron data is not trivial and crystallographic methods have been modified to take account of the complexities, such as the Rietveld technique Chapter 4 and the pair distribution function Chapter Information is not only obtained about solids but about liquids, melts and aqueous solutions as well Chapters In fact this field, approached with inelastic scattering Chapter 10 and small angle scattering Chapter 13 is opening unprecedented opportunities for earth sciences.
Small angle scattering also contributes information about microstructures Chapter Neutron diffraction has become a favorite method to quantify residual stresses in deformed materials Chapter 16 as well as preferred orientation patterns Chapter The volume concludes with a short introduction into neutron tomography and radiography that may well emerge as a principal application of neutron scattering in the future Chapter Chapter 1.

Redfern, p. The crystal and magnetic structures of polycrystalline BiCrO 3 were determined by the Rietveld method from neutron diffraction data measured at temperatures from 7 to K. Refined magnetic moments at 7, 50, and 80 K are 2.
Electrochemical Tests For the long-term cycling experiments, the same cylindrical cell configuration as for the neutron diffraction measurements was used, but with standard LP30 electrolyte instead of the deuterated electrolyte. Murli C. Robert, R. They tend to drown in the inelastic background. Thus, the strongest underestimation of the errors of the refined parameters as provided directly by the refinement program is most probably by a factor of 1. Figure 2.
The structure refinements revealed no deviation from stoichiometry in BiCrO 3.
