We propose that alkali-metal migration in oxide glasses at low temperature occurs through SiO2 units structurally relaxed by irradiation. With a combination of percolation and diffusion equations, we are able to explain all experimental data obtained by Pantano et al.

Abstract
We propose that alkali-metal migration in oxide glasses at low temperature occurs through SiO2 units structurally relaxed by irradiation. With a combination of percolation and diffusion equations, we are able to explain all experimental data obtained by Pantano et al.
