Study of D0 decays into K̄0 and K̄*0

Using the CLEO II detector at CESR we have studied D 0 decays into final states with a K 0 or K* 0 , and have measured branching ratios for the decay modes D 0 → (K 0 /K* 0 )π 0 , η,η'. These results are compared with predictions of various charm decay models, and contributions of final-state interactions are discussed
