Abstract
The correlation data for identical K-mesons produced in S + Pb collisi ons at 200 GeV/c by NA44 Collaboration are analysed by theoretical for mulae with the long-range correlation. It is found that interaction ra nge (the root mean square (rms)) of K-K- is smaller than that of K+K+: R(rms)(K-K-) approximate to(5.3 similar to 6.2 fm)<R(rms)(K-+K+)appro ximate to(6.9-8.0 fm). This suggests that in nuclear collisions the an ti u-quarks are produced in smaller space region than the u-quarks.
