The extremely neutron-deficient isotope 178Pb has been produced. The GREAT spectrometer at the focal plane
position of the gas-filled separator RITU was used to study the α decay of 178Pb and its α-decay chain through
α-α correlations. The α decay was measured to have an energy and half-life of Eα= 7610(30) keV and t1/2 =
0.21+0.21
−0.08 ms, respectively. The half-life is consistent with recent theoretical calculations using the Coulomb
and proximity potential model. The α-decay reduced width and hindrance factor for 178Pb were deduced and
correspond to an unhindered l = 0 transition. In addition, the mass excess of 178Pb and the α-decay Q value
were calculated from the experimental results and compared to theoretical values.
