WebNov 11, 2011 · The Refractive Index of Silicon at Gamma Ray Energies D. Habs, M.M Günther, M. Jentschel, W. Urban The index of refraction n (E_ {\gamma})=1+\delta (E_ {\gamma})+i\beta (E_ {\gamma}) is split into a real part \delta and an absorptive part \beta. WebAmong the three, alpha is the weakest, and gamma is the strongest type of radiation. Gamma radiation or gamma ray is an extremely high-frequency radioactive radiation consisting of high-energy photons. It was first discovered by a French chemist and physicist, Paul Villard, in 1900. It was named gamma ray by Ernest Rutherford in 1903.
