graphite. Typically, diffusion, the speed of a particle’s movement on a surface, is a thermally activated process. The higher the temperature, the faster a particle is able to move. At lower temperatures ... movement of a liquid, and there was very little change in its diffusion rate from high to low temperatures, compared to the sample and other ...

share of experiments in this field of science has been performed on PF2 in the last quarter of a century. As a consequence, all scientific areas exploitable with UCN have been covered: the lifetime of the ... key quantities of weak interaction with high precision, but also a key parameter to big-bang nucleosynthesis (BBN) models. By searching for a ...
