The W-exchange process B s →η c (J/ψ)D is studied with the perturbative QCD approach. Three kinds of wave functions for B s meson and two forms of wave functions for charmonium are considered. It is estimated that the branching ratios for , η c D, , J/ψD decays are of the order of 10−7, 10−8, 10−8, 10−9, respectively, where the largest uncertainty is from wave functions. There is a possibility for measuring these decays in the near future.
