TL;DR: In this article, the authors combine modern theoretical calculations with evaluated selected experimental data to produce a comprehensive data resource of K- and L-x-ray transition and absorption edge energies for all of the elements from neon to fermium.

TL;DR: The Bragg Crystal Spectrometer (BCS) as discussed by the authors is one of the instruments which makes up the scientific payload of the SOLAR-A mission, which employs four bent germanium crystals, views the whole Sun and observes the resonance line complexes of H-like FexxvI and He-like FAxv, Caxix, and Sxv in four narrow wavelength ranges with a resolving power between 3000 and 6000.

TL;DR: In this paper, the Avogadro constant was improved to 6.0220943 by using optical interferometry of the crystal repeat distance, which represents a more than thirty-fold reduction in the uncertainty of previous direct measurements.

TL;DR: An analytical approach to investigating the periodic nonlinearity that arises from nonideal laser sources and imperfections of optical components limits the accuracy of displacement measurements in heterodyne interferometry at the nanometer level.
