%X we compute important ratios between decay widths of some exclusive two-body nonleptonic and semileptonic b decays, which could be test of factorization hypothesis. we also present a summary of the expressions of the decay widths and differential decay rates of these decays, at tree level, including l = 0 (ground state), l = 1 (orbitally excited) and n = 2 (radially excited) mesons in the final state. from a general point of view, we consider eight transitions, namely h p,v, s, a, a' , t, p (2s), v (2s). our analysis is carried out assuming factorization hypothesis and using the wsb, isgw and clfa quark models.
