A study of B meson decays to two-body final states containing a K~0 is presented. The decay B~0 → K~0K~0 has been observed for the first time and an upper limit on B~+ → K~0K~+ has been set. In addition, a search for the D_(sJ)~*(2632)~+ state recently reported by the SELEX Collaboration at FNAL has been performed in the D_s η, D~0K~+ and D~(*+)K_S decay modes. No signal is observed in the searched channels.
