摘要：
We employ the Isgur et al.'s method to evaluate the contribution from the final state interactions to D0 --> KKBAR and pipiBAR explicitly, then determine the contribution from the W-exchange diagram. We found that the new measurements confirm the smallness of the W-exchange contribution, but indicate that it may have a complex phase relative to the spectator diagram.
