Josephson tunneling I-V characteristics have been observed in break j unctions of oxygen-annealed Bi2Sr2CaCu2Os (Bi-2212 ) single crystals, with foR. ~ 21.3 mV, and with a sharp quasipartiele edge at 2zt ~ 2 × 20 mV. This demonstrates that low values of the IoR. product, thus far as observed in HTS
