Degrees Awarded: Description of Research & Links: Low energy photons (visible laser light) are back-scattered from a high energy electron beam to produce high energy photons (aka gamma rays). It is like hitting a ball (photon) with a bat (electron) and accelerating the ball to very high speeds. The gamma ray photons are aimed at polarized proton and deutron (bound state of a proton and a neutron) targets and by looking at the scattering pattern you can obtain information on the spin structure of the nucleons (protons and neutrons). |
