The main optical properties of X-ray wavefields at the Bragg incidence are then reviewed: Pendellsung , shift of the Bragg peak, fine structure of Kossel lines, standing waves, anomalous absorption, paths of wavefields inside the crystal, Borrmann fan and double refraction. Lastly, some of ...
MILLIMETER WAVESDIAGNOSTICSThe imaging properties of the soft-X-ray microscopes composed of a Schwarzschild objective and a grazing incidence mirror condenser are discussed. Fundamental formulae on the partially coherent transfer function, the resolution of a two-point object and the edge response have ...

The crystal structures of TeSeO thin films were characterized by a grazing-incidence x-ray diffractometer (GIXRD). As shown in Fig. 1b, the TeSeO samples with relatively high Te content (Te:Se ≥ 7:3) show a polycrystalline nature, while the Se-rich samples (Te:Se ≤ 6:4) ...
X-RAY SPECTROSCOPIC DIAGNOSIS OF A WIND-COLLIMATED BLAST WAVE AND METAL-RICH EJECTA FROM THE 2006 EXPLOSION OF RS OPHIUCHI Chandra HETG observations of RS Ophiuchi at day 13.9 of the 2006 outburst reveal a rich spectrum of emission lines from abundant ions formed over a wide te... JJ Drake...
The elastic properties of minerals control the stress–strain relationship under elastic loading and are related to understanding strength, hardness, brittle/ductile behavior, damage tolerance, and mechanical stability. The elastic modulus controls the propagation of elastic waves, including the seismic anis...

. The dislocation densities of the grown crystal were estimated using etch pit density (EPD) analysis and the process is explained elsewhere in detail. [13] The grown crystal was oriented in the [1 0 0] direction using X-ray technique and wafers were cut using a diamond saw machine. The...
Along with other exper- imental methods to probe phonon excitations such as neutron scattering3, x-ray scattering4 and electron energy-loss spectroscopy5, Raman spectroscopy has been widely used to characterize lattice motions because of its easy-and-quick application and high sensitivity even for ...
Below ωp, the incident waves will be mostly reflected. The ωp values for the 99 crystals are listed in Table S3. The highest ωp is identified to be in 85-Lu5GaS9 at 31.10 eV, while the lowest ωp is in 63-Ag2SnSe3 at 15.50 eV. Mechanical properties Mechanical properties of ...
