Optical Dispersion Parameters of (PMMA doped red methyl) Irradiated by Gamma Rays

Abstract

          The dispersions of the refractive indices of (PMMA doped red methyl) films Irradiated by Gamma Rays have been determined using the Wemple-DiDomenico model . The oscillator energy E₀ , dispersion energy E_d , absorption coefficient and skin depth are calculated before and after irradiated . Drude’s theory of dielectrics used to calculate carrier concentration N_{opt .}  It's found that N_opt increases after irradiation .
