The extremely neutron-deficient isotope Pb-178 has been produced. The GREAT spectrometer at the focal plane position of the gas-filled separator RITU was used to study the alpha decay of Pb-178 and its alpha-decay chain through alpha-alpha correlations. The alpha decay was measured to have an energy and half-life of E-alpha = 7610(30) keV and t(1/2) = 0.21(-0.08)(+0.21) ms, respectively. The half-life is consistent with recent theoretical calculations using the Coulomb and proximity potential model. The alpha-decay reduced width and hindrance factor for Pb-178 were deduced and correspond to an unhindered Delta l = 0 transition. In addition, the mass excess of Pb-178 and the alpha-decay Q value were calculated from the experimental results and compared to theoretical values.
