Using the light cone QCD Sum Rules Method, we study the rare B -> nu barnu
gamma decay and and find that the branching ratios are, B(B_s -> nu barnu
gamma) = 7.5 10^{-8}, B(B_d -> nu -> nu gamma) = 4.2 10^{-9}. A comparision of
our results, on branching ratio, with constituent quark and pole dominance
model predictions are presented.
