  High-mass diffractive production of protons on the deuteron target is studied
in the perturbative QCD in the BFKL approach. Leading order rearrangement
contribution and the standard triple pomeron (the impulse approximation) are
studied. In the perturbative limit $\alpha_s\to 0$ the rearrangement
contribution dominates. Numerical estimates at realistic values of $\alpha_s$
and energies strongly depend on assumptions made about the behavior of the
pomeron attached to the proton due to unitarization. They indicate that
irrespective of these assumptions in the realistic situation the rearrangement
and triple pomeron contributions turn out to be of comparable magnitude due to
large dimensions of the deuteron.
