A Combined Fit of X-ray/Neutron Total Scattering, EXAFS, and Electron Diffuse Scattering in RMCProfile: User Manual
نویسنده
چکیده
Local-structure scattering refinements using a simultaneous fit of x-ray/neutron total scattering, EXAFS, and diffuse scattering in electron diffraction are implemented as an extension to the RMCProfile software Version 6. Users should refer to the main RMCProfile manual for this version for details regarding RMC refinements using total scattering data alone. A user is expected to have a reasonable knowledge of EXAFS phenomena and be experienced in conventional EXAFS local-structure refinements. Relevant information, including tutorials, can be found at http://cars9.uchicago.edu/~ravel/software/. Likewise, a reasonable knowledge of electron diffraction is required.

A STUDY OF GAMMA RAY EXPOSURE BUILDUP FACTORS IN STRATIFIED SHIELDS FOR POINT ISOTROPIC SOURCES, INCLUDING THE EFFECTS OF INCOHERENT AND COHERENT SCATTERING
The effects of including incoherent (bound-electron) and coherent (Rayleigh) scattering in exposure buildup factor calculations for point isotropic gamma ray sources, penetrating a two-layer water-lead shield have been investigated in the gamma ray energy (E?) range of 40 keV to 3 MeV. Incoherent scattering decreases the values of these factors in both layers up to E? ~ 200 keV and the effect i...
