Popis:	Experimental results are delivered on iron redistribution in silica for proton irradiation followed by thermal annealing. Iron ions are initially implanted into silica at room temperature. Proton irradiation is performed at different temperatures. It is demonstrated, in particular, that radiation-induced migration of iron is more efficient at low temperature. Iron surface segregation and capture of iron by sinks in silica subsurface region during thermal annealing are speculated in terms of diffusion-alternative-sinks problem.
