dc.descriptionThe single- and multi- particle inclusive spectra for strongly inhomogeneous thermal boson systems are studied using the method of statistical operator. The thermal Wick's theorem is generalized and the analytical solution of the problem for an boost-invariant expanding boson gas is found. The results demonstrate the effects of inhomogeneity for such a system: the spectra and correlations for particles with wave-lengths larger than the system's homogeneity lengths change essentially as compared with the results based on the local Bose-Einstein thermal distributions. The effects noticeable grow for overpopulated media, where the chemical potential associated with violation of chemical equilibrium is large enough.
dc.description23 pages, 2 ps figures, uses hip-artc.sty, will be published in Heavy Ion Physics. The paper is minor modified version of the unpublished preprint Yu.M.Sinyukov, ITP-93-8E, Kiev, 1993. Here was done firstly the interpretation of the HBT radii as the lengths of homogeneity in radiating systems
