SPECTROSCOPIC investigations on the scattering of light in crystals show very plainly that their vibration spectra have a discrete structure manifesting itself as a set of lines with sharply defined ...

Insight-HXMT’s discovery of the fundamental electron cyclotron absorption line near 146 keV for the first Galactic ultraluminous X-ray pulsar Swift J 0243.6+6124. Neutron stars have the strongest ...

XES is an element-specific method primarily used to analyze the partially occupied electronic structure of materials. The technique is one of the photon-in-photon-out spectroscopies in which an ...
