Isomer spectroscopy in ¹³³Ba and high-spin structure of ¹³⁴Ba

NUCLEAR REACTIONS ¹²⁴Sn(¹³C, X)¹³³Ba/¹³⁴Ba, E=55 MeV from FN tandem accelerator at Cologne; ²⁰⁸Pb(¹³⁶Xe, X)¹³⁴Ba, E=6.84 MeV/nucleon from PIAVE+ALPI accelerator complex at LNL-Legnaro; measured Eγ, Iγ, γγ-coin, γγ(θ), half-lives of isomers by γγ(t) using eight HPGe and 12 LaBr₃(ce) detectors at Cologne, and magnetic spectrometer PRISMA with AGATA array at Legnaro. ^133,134Ba; deduced high-spin levels, isomers, J, π, multipolarities, alignments, bands, backbending, configurations, B(E1), B(E2). Comparison with shell-model calculations for ¹³⁴Ba, and with previous experimental results. Systematics of positive- and negative-parity yrast states in N=78 nuclei: ¹³⁰Te, ¹³²Xe, ¹³⁴Ba, ¹³⁶Ce, ¹³⁸Nd, ¹⁴⁰Sm, ¹⁴²Gd, and Z=56 nuclei: ^{126,128,130,132,134,136,138}Ba.

NUCLEAR STRUCTURE ¹³⁴Ba; calculated levels, J, π using GCN50:82, SN100PN, SNV, PQM130, and realistic SM interactions. Comparison with experimental data.
