Abstract

The Crystal Ball detector at the e⁺e^- storage ring DORIS II has been used to analyze exclusive semileptonic decays of B mesons produced at γ(4 S) energies. The decay B→evD^* has been observed with a branching ratio of (7.0±1.8±1.4)% using the π°D decay mode of the D^*. In addition we have searched for the exclusive semileptonic decay B^±→e^±vπ⁰. We find an upper limit on B^±→e^±vπ⁰ of 0.22% at the 90% CL.
