Shape coexistence at the proton drip-line: First identification of excited states in ¹⁸⁰Pb

NUCLEAR REACTIONS ⁹²Mo(⁹⁰Zr, 2n)¹⁸⁰Pb, E=400 MeV; measured Eγ, Iγ, (recoil)γ-, (recoil)αγ coin using the JUROGAM II array and recoil-decay tagging (RDT) technique. ¹⁸⁰Pb; deduced levels, J, π, band. Comparison with beyond-mean-field theoretical calculations. Z=82, A=180-208; systematics of spherical, prolate and oblate structures.

RADIOACTIVITY ¹⁸⁰Pb(α); measured Eα and half-life. ^176,177Hg, ^179mTl(α); measured Eα.
