The paper presents experimental results for optical range silica luminescence induced by 420 keV molecular hydrogenion bombardment. Ion beam from van der Graaf accelerator impinged on silica target, varying absorption dose fromnonir radiated state up to 4.35·1010 Gy. We focused upon evolution of spectrum shape and angular spectral characteristics (observation angle 0–70°) depending on absorption dose. The influence of absorption dose growth on luminescence indicatrix measured for wavelengths 456 and 644 nm was studied.
