Bose–Einstein correlations of charged kaons in central Pb+Pb collisions at $E_{beam}$ =158 GeV per nucleon

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 data. The measured

m_\perp

dependence for kaons and pions is consistent with collective transverse expansion of the source and a freeze-out time of about 9.5
