Notes: Abstract We have studied $$D_s^ + \to K_0^{* + } \bar K^0$$ and $$D_s^ + \to \bar K_0^{*0} K^ +$$ decays in the factorization of the hadron currents approximation. The spectator model leads the decays have different but negligible branching ratios. We show, however, that the inclusion of annihilation contribution can enhance the branching ratios. We predict that $$B(D_s^ + \to \bar K_0^{*0} K^ + )$$ and $$B(D_s^ + \to K_0^{* + } \bar K^0 )$$ could be around 2%.
