A method is proposed for resolving experimentally the details of the r
esonant fluorescence spectrum of a Bose condensate within a homogeneou
s line whose width is greatly increased because of collective effects.
A discussion is presented concerning the application of this method f
or determining the shifts of the resonant frequencies of the transitio
ns in the condensate as compared to the usual case of nondegenerate at
om ensembles. (C) 1997 American Institute of Physics. [S1063-7850(97)0
