125Gamma-ray astronomy — is the astronomical study of the cosmos with gamma rays. Early history Long before experiments could detect gamma rays emitted by cosmic sources, scientists had known that the universe should be producing these photons. Work by Eugene Feenberg… …
126X-ray magnetic circular dichroism — (XMCD) is a difference spectrum of two x ray absorption spectra (XAS), one taken with left circularly polarized light, and one with right circularly polarized light. By closely analyzing the XMCD spectrum, information can be obtained on the… …
127X-ray microtomography — Microtomography (commonly known as Industrial CT Scanning), like tomography, uses x rays to create cross sections of a 3D object that later can be used to recreate a virtual model without destroying the original model. The term micro is used to… …
128X-ray spectroscopy — is a gathering name for several spectroscopic techniques for determining the electronic structure of materials by using x ray excitation. X ray emission spectroscopy Karl Manne Georg Siegbahn from Uppsala, Sweden (Nobel Prize 1924), who… …
