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 ...

Transitions between different electronic energy levels in elements occur at unique energies and intensities, giving each element a distinctive emission spectrum. When the energy of an incident photon ...

A set of five gas discharge tubes are arranged such that when they are touched with a Tesla coil, their characteristically colored emission spectra are seen. The Tesla coil can burn your skin on ...
