Description

The α decay of /sup 194/Pb [E/sub α/ = 4.64 +- 0.02 MeV, α branch = (7.3 +- 2.9) x 10/sup -6/%] was identified for the first time, and a comprehensive decay scheme was constructed for the isotope's β-decay branch. This scheme consists of 29 excited levels built on the 2- /sup 194/Tl ground state and incorporates 91 γ-ray transitions. Based on the decays of several strong transitions, the half-life of /sup 194/Pb was measured to be 12.0 +- 0.5 min. The /sup 194/Pb α reduced width, calculated with these data, is less than those of Pb, Hg, and Pt nuclei with A≤192, indicating that the Z = 82 gap is perhaps being restored for N≥112
