Abstract
The temperature dependence of the non-ergodicity parameter of a strongglass former, B2O3, has been investigated using neutron scattering. A clear change is observed at a temperature ( ∼ 800 K) well above theglass-transition temperature ( ∼ 523 K), and a complementary behaviour isobserved for the strength of a fast relaxation process. The resultsdirectly shows the existence of a dynamic transition in the super-cooled melt of a strong network glass former. The transition, which is corroborated by the analysis of sound velocity and viscosity data, resembles that predicted by the mode coupling theory, and thereby shows the applicability of thistheory even to strong glass formers.
