The strong interaction shift in the 1S state is −4.8 eV, corresponding to a scattering length a( πd) = −(0.052 −0.017 +0.022) m π −1, in agreement with recent calculations. The intensity ratio K α/K total = 0.548 ± 0.015....
In this study, we present a combined small-angle neutron and X-ray scattering (SANS and SAXS) study of the nanoscale structure of cortical bone specimens from three different species. The variation of the scattering cross section of elements across the periodic table is very different for neutron...
For Li and Al, curves are given for various scattering angles. The results are similar to those obtained by previous observers for carbon, the shift of the maximum intensity of the modified band agreeing with the theory of A. H. Compton. Simultaneous irradiation by two x-ray tubes permitted...
Quenching of vibrational excitations in resonant inelastic X-ray scattering (RIXS) spectra of liquid acetic acid is observed. At the oxygen core resonance associated with localized excitations at the O–H bond, the spectra lack the typical progression of vibrational excitations observed in RIXS spectra...

X-ray small angle scattering experiments, using a pin hole SAXS camera with Synchrotron radiation source, have been performed to study the conformational changes of lyophilized samples of Apo-, Mono-, and Diferric- human transferrin. We report the experimental evidence that the analysis of the scat...
X-Ray-Scattering Study of the Fast-Ion Conductor β"-Alumina The ion-ion correlations and a new crystal-structure determination of β''- and β''-alumina reveal that the conducting ions are distributed between two independent sites instead of one given by previous work: Beevers-Ross-anti-...

Summary Small-angle X-ray scattering (SAXS) technique is useful to determine the crystalline and amorphous thicknesses and their distributions, as well as the crystal perfection. The study of polymer morphology aims to elucidate the organization of crystalline domains. This chapter describes the fundam...
