Abstract
Using a recoil corrected version of the MIT bag model, we compute the relevant form factors and decay rates for the exclusive semileptonic decays\(B \to De\bar v_e and B \to D*e\bar v_e \). Our results are similar to other quark model calculations, but we find that theD * mode is suppressed due to the influence of the spectator quark. TheD *′ s produced are almost unpolarized in this model.
