Abstract

The

γ

decay from the

2_{3}^{+}

state at about 2-MeV excitation in the nuclei

{}^{140}{Ba}

{}^{142}{Ce}

, and

{}^{144}{Nd}

, with 84 neutrons, is shown to be consistent with its identification as the lowest state of mixed symmetry in the U(5) limit of the neutron-proton version of the interacting-boson model.
