The exclusive decay modes B{r_arrow}K{gamma}{gamma} and B{sub s}{r_arrow}{eta}({eta}{sup {prime}}){gamma}{gamma} are shown to have significant branching ratios of approximately 0.5{times}10{sup {minus}7}. This first calculation of these modes employs a model based on a cascade transition B{r_arrow}V{gamma}{r_arrow}P{gamma}{gamma} for estimating the long-distance contribution and the process b{r_arrow}s{gamma}{gamma} for the short-distance one. {copyright} {ital 1997} {ital The American Physical Society}
