Results for the Cabibbo suppressed semileptonic decays D0 → pi−e+ nu and D0 → pi− mu+ nu (charge conjugates are implied) are reported by Fermilab photoproduction experiment E687. We find 45.4 ± 13.3 events in the electron mode and 45.6 ± 11.8 in the muon mode. The relative branching ratio BR(D0 -> pi- l+ nu)/BR(D0 -> K- l+ nu) for the combined sample is measured to be 0.101 ± 0.020 (stat.) ± 0.003 (syst.).
