[en] The first direct study of the decay B^- → D^*0l^-ν-bar was performed leading to BR(B^- → D^*0l^-ν-bar)=(5.8±1.4±1.3)% and |V_cb|=0.044±0.009. Partial reconstruction of D^*+ decays allowed to observe more than 2000 of (B⁰)-bar → D^*+l^-ν-bar decays and to measure precisely the branching ratio. For the first time the low energy part of lepton spectrum in semileptonic B decays has been measured. It agrees nicely with spectator model predictions. Evidence for the Ω_c baryon has been obtained. The decay D_s^**+(2536) → D^*0 K⁺ was observed. (author) 13 refs.; 8 figs
