Abstract
Two-particle interferometry of positive kaons is studied in Pb + Pb collisi ons at mean transverse momenta [p(T)] approximate to 0.25 and 0.91 GeV/c. A three-dimensional analysis was applied to the lower p(T) data, while a two -dimensional analysis was used for the higher p(T) data. We find that the s ource-size parameters are consistent with the m(T) scaling curve observed i n pion-correlation measurements in the same collisions. and that the durati on time of kaon emission is consistent with zero within the experimental se nsitivity.
