We describe the long-time annealing behaviours of radiation-induced atomic hydrogen in OH-containing high-purity silica in terms of both classical and fractal kinetic equations controlling the dimerization process of the radiolytic H-0. Some new features about the possible hydrogen diffusion mechanisms in medium-range structural channels embedded in an otherwise amorphous matrix are discussed.

Abstract
We describe the long-time annealing behaviours of radiation-induced atomic hydrogen in OH-containing high-purity silica in terms of both classical and fractal kinetic equations controlling the dimerization process of the radiolytic H-0. Some new features about the possible hydrogen diffusion mechanisms in medium-range structural channels embedded in an otherwise amorphous matrix are discussed.File in questo prodotto:
