  The PHENIX experiment measured Bose-Einstein quantum-statistical correlations
of charged kaons in Au+Au collisions at $\sqrt{s_{\text{NN}}}$ = 200 GeV. The
correlation functions are parametrized assuming that the source emitting the
particles has a L\'evy shape, characterized by the L\'evy exponent $\alpha$ and
the L\'evy scale $R$. By introducing the intercept parameter $\lambda$, we
account for the core-halo fraction. The parameters are investigated as a
function of transverse mass. The comparison of the parameters measured for
kaon-kaon with those measured from pion-pion correlation may clarify the
connection of L\'evy parameters to physical processes.
