We present the first statistically meaningful results from two-K interferometry in heavy-ion
collisions. A model that takes the effect of the strong interaction into account has been used to fit
the measured correlation function. The effects of single and coupled channel were explored. At the
mean transverse mass (mT) = 1.07 GeV, we obtain the values R = 4.09 + 0.46(stat.) + 0.31(sys)
fm and A = 0.92 + 0.23(stat) + 0.13(sys), where R and A are the invariant radius and chaoticity
parameters respectively. The results are qualitatively consistent with mT systematics established
with pions in a scenario characterized by a strong collective flow.PACS numbers: 25.75.Gz
