Doubly magic ²⁰⁸Pb: High-spin states, isomers, and E3 collectivity in the yrast decay

NUCLEAR REACTIONS ²⁰⁸Pb(⁴⁸Ca, X), E=430 MeV; ²⁰⁸Pb(²⁰⁸Pb, X), E=1440 MeV; measured Eγ, Iγ, γγ-coin, γγ(θ), half-lives of isomers by γγ(t), in-beam and off-beam Iγ using Gammasphere array at ATLAS-ANL facility. ²⁰⁸Pb; deduced high-spin levels, new isomers, J, π, total electron-conversion coefficients from intensity balances, multipolarities, mixing ratios, B(E1), B(E2), B(E3), B(M1), B(M2), 1p-1h yrast and near-yrast states and their rotational interpretation, 2p-2h states. Comparison with shell-model calculations.
