First spectroscopic information from even-even nuclei in the region "southeast" of ¹³²Sn: Neutron-excitation dominance of the 2⁺₁ state in ¹³²Cd

NUCLEAR REACTIONS ⁹Be(¹³⁴Sn, ¹³²Cd), E not given, [secondary ¹³⁴Sn beam from W(²³⁸U, F), E=345 MeV/nucleon primary reaction and using BigRIPS fragment separator]; measured reaction residues through identification by TOF, Bρ, ΔE, and total kinetic energy (TKE) using the ZeroDegree spectrometer, Eγ, Iγ, (particle)γ-coin using DALI2 array at RIBF-RIKEN facility; ¹³²Cd; deduced levels, J, π, proton-neutron configuration mixing in the first 2+ state. Comparison with mean-field calculations. Systematics of experimental and theoretical first 2+ energies in N=84, Z=48-66, Z=48, N=50-82, and Z=52, N=54-86 nuclei.
