Abstract
We have determined the cross-section r for color center generation under single Br ion impacts on amorphous SiO2. The evolution of the cross-sections, r(E) and r(Se), show an initial flat stage that we associate to atomic collision mechanisms. Above a certain threshold value (Se>2 keV/nm), roughly coinciding with that reported for the onset of macroscopic disorder (compaction), r shows a marked increase due to electronic processes. In this regime, a energetic cost of around 7.5 keV is necessary to create a non bridging oxygen hole center-E0 (NBOHC/E0) pair, whatever the input energy. The data appear consistent with a non-radiative decay of self-trapped excitons
