Possible wobbling phenomenon in ¹²⁵Xe

NUCLEAR REACTIONS ⁸²Se(⁴⁸Ca, 5n)¹²⁵Xe, E=205 MeV; measured Eγ, Iγ, γγ-coin, γγγ-coin, γγ(θ). ¹²⁵Xe; deduced levels, J, π, δ, directional correlation of oriented nuclei ratios (DCO ratios), B(E2)_out/B(E2)_in, B(M1)_out/B(E2)_in, wobbling energy. Concluded that the set of 4 negative-parity bands originates from the coupling of a h_11/2 quasineutron with the ground state configuration of the even-even core. Comparison to triaxial projected shell model calculations. Systematics of experimental and calculated wobbling energy values for ¹²⁵Xe, ¹²⁷Xe, ¹³³La, ¹³³Ba, ¹³⁵Pr.
