Abstract
The strong spin-dipole relaxation, accompanying BEC in a gas of atomic hydr ogen, determines the formation of a quasistationary state with a flux of pa rticles in the energy space to the condensate. This state is characterized by a significant enhancement of the low-energy distribution of non-condensa te particles? resulting in the growth of their spatial density in the trap. This growth leads to the anomalous reconstruction of the optical spectral properties of non-condensate particles. (C) 2000 Elsevier Science B.V. All rights reserved.
