摘要：

The authors examined synergistic effects during sequential irradiation of zinc oxide powders by electrons and protons with an energy of 100 keV. Two modes were employed: 1) electrons followed by protons; 2) protons followed by electrons. It was found that the additive coefficient, when determined by the change in the integral absorption coefficient of solar radiation and calculated via diffuse reflectance spectra within 0.3-2.1 mu m, depends on the irradiation mode and on the type of radiation-induced defects (i.e., intrinsic point defects or free electrons).
