Band structures, lifetimes, and shape coexistence in ¹³⁰La

NUCLEAR REACTIONS ¹²¹Sb(¹²C, 3n)¹³⁰La, E=54 MeV; measured Eγ, Iγ, γγ-coin, γγ(θ)(ADO), isomer and level half-lives by γγ(t) using the ROSPHERE array of 14 HPGe detectors and 11 LaBr3(Ce) scintillators at the FN Tandem accelerator of IFINHH-Bucharest. ¹³⁰La; deduced high-spin levels, J, π, bands, multipolarities, configurations, B(M1), B(E2), transition quadrupole moments, β₂ deformation parameters. Comparison with two-quasiparticle-plus-rotor model calculations, and with geometrical model of Donau and Frauendorf for B(M1) strengths.
