Magnetic excitations in the nucleon-pair shell model
,-0001,():
Magnetic transition strengths in 134Ba 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 proton-neutron TDA approximation. The M1 and M3 transition strengths are found to be consistent with results from the proton-neutron interacting boson model calculations. The results confirm that the collective magnetic properties of 134Ba are primarily due to the orbital motion of nucleons.
