Abstract
Excited states in 130Ba have been studied with the 25MeV 132Ba(p, t)130Ba reaction with 8keV energy resolution, at the Munich Q3D spectrograph. 27 excited states were observed up to 2.6MeV excitation energy, for 21 of them spin and parity being confirmed or assigned. These results complement earlier measurements concerning the systematics of 0+ states in 132Ba and 134Ba , and allow a more detailed comparison with predictions of different nuclear-structure models. The comparison with interacting boson model calculations brings additional evidence in favor of a description of this nucleus by parameters close to the O(6) symmetry.
