Colors of emission spectra are due to loosely-bound valence electrons being excited in a flame and dropping back down while emitting light. Warning! Once the flame has started, DO NOT add more ...

The first NMR spectra were first published in the same issue of Physical ... The NMR phenomenon relies on the interaction of the nuclei of certain atomic isotopes with a static magnetic field. This ...

IN his letter to NATURE of January 1 on “tomic Models and X-Ray Spectra,” Dr. F. A. Lindemann deals with the approximate agreement between the recent experiments of Mr. H. G. J. Moseley on ...

Core nuclear reaction database containing evaluated cross sections, spectra, angular distributions, fission product yields, photo-atomic and thermal scattering law data, with emphasis on neutron ...

The authors demonstrate how this framework enables the prediction of 3D atomic arrangements from XANES spectra. "Our method bridges a crucial gap between spectroscopic analysis and precise ...

This causes an absorption spectra, as shown below. Because the energy levels are the same, the lines in the emission spectra of an element are in the same position as the lines in the absorption ...

This supplement is an update of Technical Report Series No. 318, Compendium of Neutron Spectra and Detector Responses for Radiation Protection Purposes (1990), that takes into account the major ...
