Abstract—The work reports on studies of the diffuse reflectance spectra in situ recorded in vacuum for SiO2-nanoparticle-modified BaSO4 micron-sized powders in the range of 0.2–2.2 μm before and after the separate solar spectrum quanta exposure and the successive irradiation after exposure to protons with energy of 5 keV. The absence of additivity upon the separate and successive solar spectrum quanta irradiation of the examined compound is established.
