摘要：

Bose-Einstein correlations of charged kaons were measured near mid-rapidity in central Ph + Pb collisions at 158 A GeV by the NA49 experiment at the CERN SPS. Source radii were extracted using the Yano-Koonin-Podgoretsky and Bertsch-Pratt parameterizations. The results are compared to published pion and kaon data. The measured m(perpendicular to) dependence for kaons and pions is consistent with collective transverse expansion of the source and a freeze-out time of about 9.5 fm.
