Abstract
Magnetic transition strengths in Ba-134 are discussed within the framework of the nucleon-pair shell model (NPSM) truncated to the SD subspace. The S and D pairs are determined, respectively, by a variational method and a pro ton-neutron TDA approximation. The M1 and M3 transition strengths are found to be consistent with results from the proton-neutron interacting boson mo del calculations. The results confirm that the collective magnetic properti es of Ba-134 are primarily due to the orbital motion of nucleons.
