Amorphous silica samples have been bombarded with Ni+6 ions of 46.5 MeV to produce a large number of atomic displacements. Other samples with the same impurity content have been irradiated with electrons of 1.5 MeV. Isochronal annealings at various temperatures up to 600°C were made on the irradiated samples. Optical absorption spectra, induced with these treatments, in the UV region up to 190 nm have been analyzed and the relevant parameters of B2, E1’, Do and E centers have been evaluated. The comparison between results obtained from heavy ion and electron irradiated samples seems to indicate that the B2 and E bands are related to displacive efficiency of impinging particles while the E1’ and Do are related to the total energy deposition, irrespective of dpa values.
