Two sets of new results are presented which confirm the occurrence of a Bose-Einstein condensation of biexcitons in CuCl. First, luminescence spectra recorded under well controlled conditions yield the distribution function of the particles, which takes the form of a strongly degenerate Bose-Einstein distribution under increasing excitation, with mu up to 0. Second, probe particles injected into the system in the presence of the presumed condensate are observed to coalesce into it.
