摘要

Through ¹²²Sn(¹⁶O, 4n), ¹³⁰Te(¹¹B, 5n) and ¹⁰⁷Ag(¹⁹F, 1p3n) heavy-ion nuclear reactions and in-beam γ-ray spectroscopy technique, high spin states of ¹³⁴Ce, ¹³⁶La and ¹²²Cs have been studied. The previous level schemes have been extended. The observed results show that the collective band structures in these three nuclear were affected by the shape-driving effects. The shape coexistence with different γ deformations has been observed in ¹³⁴Ce. In ¹³⁶La, the πh_11/2 ⊗ νh_11/2 band was updated and its character has been discussed while two oblate bands with γ ∼ -60° have been established. In ¹²²Cs chiral doublet bands were proposed. The magnetic rotational bands reported in a recent paper in ¹³⁴Ce were not confirmed by our experiment.
