Abstract
The temperature dependence of relaxation mechanisms in solids are examined and compared with experimental observations. Evidence is presented for thermally activated processes, quantum mechanical tunnelling relaxation, thermally activated tunnelling and critical behavior relaxation. It is shown that the Williams-Landel-Ferry function is an approximation to the power law decay of relaxation that has been observed in the alpha region of glass-forming systems.Keywords
