摘要: The 104,106,108Ru nuclei have been produced as fission fragments following the fusion reaction 28Si + 176Yb at 145 MeV bombarding energy; prompt gamma rays emitted in were detected using Eurogam II array. Their high-spin level schemes obtained, particularly several side bands extended or newly observed. Experimental results are discussed framework of both collective model and rotating mean-field approach which Gogny force is sole input. These calculations provide very good descriptions low-spin structures observed neutron-rich even-A Ru isotopes.
