摘 要: | The rotational bands up to a spin of 16h in the neutron-rich ^106Mo nucleus have been ivestigated by measuring high-fold prompt γ-ray coincidence events following spontaneous fission of ^252Cf with a Gammasphere detector array.The ground-state band,the one-phonon and two-phonon γ-vibrational bands,as well as a quasi-particle hand have been confirmed and expanded.The other four collective rotational bands,three proposed as two-quasi-particle bands and one proposed as a β-vibrational band,have been newly observed.The characteristics of these collective bands and the possible configurations for the quasi-particle bands are discussed.
