The decay property of $$^{277}$$Cn (atomic number, $$Z=112$$) produced in the $$^{208}$$Pb($$^{70}$$Zn, $$n$$) reaction was studied. The experiment was performed using the gas-filled recoil ion separator (GARIS) at the RIKEN liner accelerator facility (RILAC). The $$^{208}$$Pb target with about 630 $$mu$$g/cm$$^{2}$$ thickness was bombarded with 347.5, 351.5, and 355.5 MeV $$^{70}$$Zn beam. At the beam energy of 351.5 MeV, we observed one $$alpha$$-decay chain from $$^{277}$$Cn. The $$alpha$$-particle energy of $$^{277}$$Cn was $$11.07 pm 0.08$$ MeV and its lifetime was measured to be 0.370 ms. Including our previous result of the $$^{277}$$Cn production in 2004, the cross section of the $$^{208}$$Pb($$^{70}$$Zn, $$n$$) reaction is deduced to be $$0.17^{+0.16}_{-0.10}$$ pb.
