摘要：

We predict and analyze nontrivial relaxational behavior of magnetically trapped gases near the Bose-condensation temperature T(c). Due to strong compression of the condensate by the inhomgeneous trapping field, particularly at low densities, the relaxation rate shows a strong, almost jumplike, increase below T(c). As a consequence the maximum fraction of condensate particles is limited to a few percent. This phenomenon can be called a ''relaxation explosion.'' We discuss its implication for the detectability of Bose-Einstein condensation in atomic hydrogen.
