Complete identification of states in ²⁰⁸Pb below E_x = 6.2 MeV

NUCLEAR REACTIONS ²⁰⁸Pb(p, p'), E=14.8-18.1 MeV; ²⁰⁸Pb(d, d'), E=22.0, 24.0 MeV; ²⁰⁷Pb(d, p), E=22.0, 24.0 MeV; measured E(p), I(p), E(d), I(d), differential σ(E), σ(θ) using Q3D magnetic spectrograph at MLL-LMU-Munich and TUM-Garching. Enriched ²⁰⁷Pb target contained small amounts of ^206,208Pb. ²⁰⁸Pb; deduced levels, levels populated through seven known isobaric analog resonances in ²⁰⁹Bi, J, π, configurations, multi-particle-hole states, natural-parity states, wave function amplitudes, centroid energies for groups of states; discussed completeness of states at E<6.2 MeV. Comparison with states in ²⁰⁸Pb populated via previously studied reactions, and with evaluated data in Nuclear Data Sheets for A=208 nuclides. ²⁰⁹Bi; deduced new isobaric analog resonance at E=17.60 MeV. Comparison with shell-model calculations for 1p-1h and 2p-2h configurations. Systematics of levels in ²⁰⁷Tl, ²⁰⁹Bi, ²⁰⁷Pb and ²⁰⁹Pb.
