Optical transmission spectra of nominally pure BaWO4 and SrMoO4 and doped BaWO4:La3+ and SrMoO4:Yb3+ crystals are measured after irradiation with a 6-MeV 5-μs pulse electron beam at room temperature. It is shown that the irradiation
effect strongly depends on the crystals composition, the type, and the concentrations of doping ions. Possible mechanisms
responsible for the spectra transformations and the correspondent formulas of chemical reactions addressing these mechanisms
are proposed.
