Metastable states from multinucleon excitations in ²⁰²Tl and ²⁰³Pb

NUCLEAR REACTIONS ¹⁹⁸Pt(⁷Li, 3n)²⁰²Tl, E=31-36 MeV; ¹⁹⁷Au(²⁰⁹Bi, X), E=1450 MeV; measured Eγ, Iγ, γγ-coin, γγ(θ)(DCO), γγ(linear polarization), half-lives of isomers by γ(t) and centroid-shift method using the INGA array at IUAC-New Delhi for the ²⁰²Tl experiment, and Gammasphere array at the ATLAS-ANL facility for ²⁰³Pb. ²⁰²Tl, ²⁰³Pb; deduced high-spin levels, isomers, J, π, multipolarities, B(E2), B(E3), configurations. Systematics of energies and B(Eλ) for isomers in ^202,203,204Tl and ^203,204,205Pb. Comparison with shell-model calculations.
