Confirmation of the new isotope ¹⁷⁸Pb

RADIOACTIVITY ¹⁷⁸Pb(α)[from ¹⁰⁴Pd(⁷⁸Kr, 4n), E=358 MeV using K-130 cyclotron at Jyvaskyla]; measured Eα, αα-correlations in the α decay chain ¹⁷⁸Pb -> ¹⁷⁴Hg -> ¹⁷⁰Pt -> ¹⁶⁶Os -> ¹⁶²W -> ¹⁵⁸Hf, half-life of ¹⁷⁸Pb decay; deduced Q(α), reduced width and hindrance factor. Comparison with theoretical calculations using the Coulomb and proximity potential model. Systematics of experimental and theoretical α-decay widths and spectroscopic factors for N=88-112, Z=78, 80, 82 nuclei. ^175,176Hg, ¹⁷⁷Tl, ^179mTl, ¹⁷⁹Pb(α); observed α peaks from contaminants.
