Search for the origin of wobbling motion in the A ≈ 130 region: The case of ¹³¹Xe

NUCLEAR REACTIONS ¹³⁰Te(α, 3nγ), E=38 MeV; measured Eγ, Iγ, γγ-coin, γγ(θ). ¹³¹Xe; deduced levels, J, π, δ, mixing ratios, polarization asymmetries, γ-rays deexcitation from the oriented states (DCO) ratio, intruder νh_11/2 band structure, rotational bands, yrast bands, signature splittings, high-spin states. Comparison to triaxial particle rotor model (TPRM) and triaxial projected shell model (TPSM) calculations. Systematics of the bands structure, signature splittings - ¹²⁷Xe, ¹³¹Xe, ¹³³Ba, ¹³⁵Ce. No experimental signatures of the wobbling excitation were found in the study. Seven Compton-suppressed clover HPGe detectors of the Indian National Gamma Array (INGA) at K-130 cyclotron of the Variable Energy Cyclotron Centre (VECC, Kolkata).
