Abstract
The effect of the continuous emission hypothesis on the two-pion Bose-Einst ein correlation function is discussed and compared with the corresponding r esults based on the usual freeze-out. Sizable differences in the correlatio n function appear in these different descriptions of the decoupling process . This means that, when extracting properties of the hot matter formed in h igh-energy heavy-ion collisions from the data, completely different conclus ions may be reached according to the description of the particle emission p rocess adopted.
