The effects of resonance production on correlations in final states containing kaons in ρρ̅ annihilations at 0.76 GeVc have been in detail. We show that correlation distributions of unlike kaon pairs, KS0K±, can be completerly by resonance production. However, for like kaon pairs, KS)KS0, we require the added effects of second-order interference. Using this interference effect we are able to measure the dimensions of the emission region for kaons in ρ̅ρ annihilations at low energy as R = 0.9 ± 0.2 fm.
