REAL-SPACE MULTIPLE-SCATTERING CALCULATION AND INTERPRETATION OF X-RAY-ABSORPTION NEAR-EDGE STRUCTURE

, 1998
A self-consistent real-space multiple-scattering (RSMS) approach for calculations of x-ray-absorption near-edge structure (XANES) is presented and implemented in an {ital ab initio} code applicable to arbitrary aperiodic or periodic systems.

X-Ray Astronomy

IEEE Transactions on Nuclear Science, 1964
Although searches so far have been restricted to a few small rockets and balloons, some 40 discrete x-ray sources have already been resolved against a diffuse, nearly isotropic background radiation. The strongest source is about 2000 times as bright as the weakest detectable with present rocket instruments.
