depts.washington.eduscattering and the photoelectric effect. Both processes convert the gamma ray energy into electron energy. On average approximately one electron hole pair is produced per 30 eV of gamma ray energy deposited in the crystal. These electrons result in the release of visible light when trapped in the crystal.
The Sun in the Electromagnetic Spectrum - Stanford University
solar-center.stanford.eduThe Sun produces lots of gamma rays during fusion in its core. However, by the time these work their way through the dense interior of the Sun, they have all lost energy and emerge from the Sun as visible light waves. Gamma-rays can also be …

Spectroscopy spreads out the different wavelengths of light into a spectrum for study. Photometry measures the quantity of light in specific wavelengths or by combining all Space-Based Astronomy

Gamma Ray Spectroscopy - University of Michigan
www-personal.umich.eduThe photoelectric absorption interaction is the ideal interaction for gamma-ray spectroscopy. The photoelectron carries away most of the gamma-ray energy and then an X-ray or Auger electron carries away the remaining kinetic energy. Assuming an ideal detector, the sum of these energies will equal the energy of the original gamma-ray.
