First observation of high-spin states in ²¹⁴Po: Probing the valence space beyond ²⁰⁸Pb

NUCLEAR REACTIONS ²⁰⁸Pb(¹⁸O, X), E=85 MeV; measured Eγ, Iγ, (x ray)γ-, γγγ-coin, γ(θ), ADO ratios, level half-life by γγ(t) using Euroball IV array. ²¹⁴Po; deduced levels, J, π, yrast structure, internal conversion electron coefficients, multipolarities, configurations. Comparison with empirical shell model predictions and with systematics (levels and B(E2)) of ²¹⁰Pb, ^{210,212,214,216,218}Po.
