Abstract
Accurate solid xenon reflectance measurements in the energy range 6.2-10.8 eV are reported. The solid, confined in a closed cell (MgF2 prismatic window), has been studied in the temperature range 80-160 K. The detailed, reliable results allowed the clear observation of the n = 4[Γ(3/2)] term of the excitonic series; its evolution was followed up to 135 K where it disappears
