WebGamma rays can also interact with atomic nuclei. In the process of pair production, a gamma-ray photon with an energy exceeding twice the rest mass energy of the electron (greater than 1.02 MeV), when passing close to a nucleus, is directly converted into an electron-positron pair ( see photograph ). WebThe Fermi Gamma-ray Space Telescope ( FGST, [3] also FGRST ), formerly called the Gamma-ray Large Area Space Telescope ( GLAST ), is a space observatory being used to perform gamma-ray astronomy observations from low Earth orbit.

The image below is of the complete light spectrum. WebBye-bye, gamma ray. But this collision, while it does destroy the original gamma-ray photon, can actually help us to detect it. If the gamma ray has a high enough energy, the collision will generate a large number of subatomic particles, all of which fly forward in the same direction as the gamma ray: an air shower. And if the gamma ray has a ...

WebThe Cherenkov radiation produced by gamma rays has a distinctive pattern that can be detected using a photomultiplier tube.
