Study of the Ba-130 nucleus with the (p, t) reaction

Abstract : Excited states in Ba-130 have been studied with the 25MeV Ba-132(p, t) Ba-130 reaction with 8 keV 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 Ba-132 and Ba-134, 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.
