The amplitudes are calculated with factorization approach, and the transition form factors $A_0^{B^{\\ast}_{(s)}\\to M_1}(0)$ are evaluated within BSW model. With the reasonable approximation $\\Gamma_{tot}(B^*_{(s)})\\simeq \\Gamma(B^*_{(s)}\\to B_{(s)}\\gamma)$, our predictions of branching fractions are presented.
