Exciton Reflection Spectra of NaI Crystals. Effect of Surface Irradiation by Photons and Incidence Angle Dependence

Reflection spectra of NaI crystals cleaved in liquid helium are investigated in detail. A fine structure is discovered in the spectral region adjacent to 2S exciton resonance at the high‐energy side. It is interpreted as the manifestation of the splitting of the n = 2 exciton state which was predict...
