This b→c decay was first measured by CLEO. However, the branch fraction of B⁰→Dbar^*0 p pbar measured is one order larger than the interesting mode. With the reconstruction of nbar established, this will be measured using Bele II data. The reconstruction, particle identification and the measurement will be presented in the talk.
