Abstract
Many glass formers show the simultaneously existence of two or more relevant elementary processes (α, β, …). The extrapolation of α and β JG (Johari-Goldstein) processes to higher temperatures leads often to a bifurcation like behavior of these processes. It will be predicted that in general a crossing or a real bifurcation between an α process and β JG process is excluded. Both processes avoid each other near and above the apparent bifurcation region. Furthermore, the α process shows strong decreasing of the intensity with increasing temperature close to this regime.
