Millisecond 23/2⁺ isomers in the N=79 isotones ¹³³Xe and ¹³⁵Ba

NUCLEAR REACTIONS ²⁰⁸Pb(¹³⁶Xe, X)¹³⁵Ba/¹³³Xe/¹³²Xe/¹³⁶Ba, E=6.84 MeV/nucleon; measured Eγ, Iγ, γγ-coin, (particle)γ-coin using the Advanced GAmma Tracking Array (AGATA) for γ detection and the PRISMA magnetic spectrometer for particle identification at the PIAVE+ALPI accelerator complex of LNL-Legnaro. ¹³⁰Te(⁹Be, X)¹³²Xe/¹³³Xe/¹³⁵Ba/¹³⁶Ba, E=40 MeV; measured Eγ, Iγ, γγ-coin, off-beam γγ(θ), half-lives of isomers using the HORUS array for γ detection at the FN tandem accelerator of the University of Cologne. ^132,133Xe, ^135,136Ba; deduced high-spin levels, isomers, J, π, total conversion coefficients, multipolarities, mixing ratios, configurations, B(M2), B(E3). ²¹⁴Po; deduced mixing ratio for a transition from γγ(θ) measurement. Comparison with previous experimental data, and with large-scale shell model calculations using the SM, GCN50:82, SN100PN and SN100-KTH interactions. Systematics of levels, J, π, transition probabilities and isomers in N=79 isotones of ¹²⁹Sn, ¹³¹Te, ¹³³Xe, ¹³⁵Ba, ¹³⁷Ce, ¹³⁹Nd, ¹⁴¹Sm, ¹⁴³Gd.

NUCLEAR STRUCTURE ¹³³Xe, ¹³⁵Ba; calculated levels, J, π, configurations using large-scale shell model with SM, GCN50:82, SN100PN and SN100-KTH interactions. Comparison with experimental data.
