The Si matrix of two SiTaSi2 in situ composites grown in the 111 direction have been characterized by means of triple axis diffractometry using synchrotron radiation with photon energies of 120 and 160 keV. The Si matrix is compressed in the growt

High-q-resolution diffraction experiments performed with 100 keV synchrotron radiation on the identical ${\mathrm{SrTiO}}_{3}$ crystal used in neutron and x-ray-scattering experiments before, unambiguously show that the bulk critical scattering above

The use of hard X-rays (60–300 keV) for diffraction studies of disordered materials has several advantages: higher resolution in direct space, smaller correction terms, removal of truncation effects, the possibility for operating in extreme environ

The absorption of 150 keV synchrotron radiation in matter is weak and, as normally done with neutrons, bulk properties are studied in large samples. However, the k-space resolution obtained with a Triple Crystal Diffractometer (TCD) for high energy s

Diffraction of high‐energy synchrotron radiation at energies above 100 keV combines advantages of conventional x‐ray diffraction and neutron diffraction. For hard x rays absorption in matter is weak with typical mean free paths of several millime
