Branching ratios for

Abstract. We calculate the so-called hard spectator corrections in

B \to K^* \gamma

{\cal O} (\alpha_s)

and

in the leading-twist approximation to the decay widths for

B \to \rho \gamma

B \to K^{*} \gamma

decays in next-to-leading order in the Large Energy Effective Theory

and

Light-cone distribution amplitudes of the ground state bottom baryons in HQET
