摘要：

We study the loop induced rare decays B-s(B-d) --> gamma nu<(nu)over bar> within the standard model. Both constituent quark model and pole model are used and the branching ratios turn out to be of the orders of 10(-8) for B-s --> gamma nu<(nu)over bar> and 10(-9) for B-d --> gamma nu<(nu)over bar>. These processes can be served to determine the decay constants of B-s and B-d.
