Abstract: (IOP)

Excited states of 127Xe were populated in the 122Sn(9Be, 4nγ) fusion-evaporation reaction at a beam energy of 48 MeV. A sequence of ΔI = 2 γ-transitions has been observed above the Iπ = 19/2+ state at 2307 keV. Spin and parity of the states belonging to this band have been assigned firmly. The dynamic moment of inertia of this band is found to be low and almost constant as a function of angular momentum. Observed experimental features along with the results of theoretical semiclassical model calculation suggest an antimagnetic rotational character for this band.
