| ABSTRACT: |
We study the structure-dependent contributions to the radiative baryonic $B$ decays of $B Ž´to {Ž´bf B}{Ž´bf Ž´bar B\'}Ž´gamma$ in the standard model. We show that the decay branching ratios of $Br(B Ž´to {Ž´bf B}{Ž´bf Ž´bar B\'}Ž´gamma)$ are $O(10^{-7})$, which are larger than the estimated values of $O(10^{-9})$ induced from inner bremsstrahlung effects of the corresponding two-body modes. In particular, we find that $Br(B^- Ž´to Ž´Lambda Ž´bar p Ž´gamma)$ is around $1 Ž´times 10^{-6}$, which is close to the pole model estimation but smaller than the experimental measurement from BELLE.
