Spectroscopy – I. Gratings and Prisms
... If we could see the whole spectrum (radio to γ–ray), then every order would completely overlap with every other order. In reality, of course, many effects limit what we can see/measure. For example, the atmosphere will eliminate most photons at shorter wavelengths than about 340nm – as well as large ...

Chapter 36 . Optical Properties of Semiconductors
... Almost all of the transitions that contribute to the optical properties of semiconductors can be described as one-electron transitions. Most of these transitions conserve the crystal momentum and thus measure the vertical energy differences between the conduction and valence bands. In the one-electr ...

Gamma spectroscopy
Gamma-ray spectroscopy is the quantitative study of the energy spectra of gamma-ray sources, in such as the nuclear industry, geochemical investigation, and astrophysics. Most radioactive sources produce gamma rays, which are of various energies and intensities. When these emissions are detected and analyzed with a spectroscopy system, a gamma-ray energy spectrum can be produced. A detailed analysis of this spectrum is typically used to determine the identity and quantity of gamma emitters present in a gamma source, and is a vital tool in radiometric assay. The gamma spectrum is characteristic of the gamma-emitting nuclides contained in the source, just as in optical spectroscopy, the optical spectrum is characteristic of the material contained in a sample.
