通过重离子熔合蒸发反应１２４Ｓｎ（１８Ｏ，４ｎ）１３８Ｃｅ研究１３８Ｃｅ的高自旋态结构．实验在中国原子能科学院Ｈ－１３串列加速器上进行，束流能量为７８ＭｅＶ经过γγ符合及方向关联比率ＤＣＯ的分析，建立了１３８Ｃｅ新的高自旋态能级图，发现了两个扁椭形变集体转动带，并对这种扁椭集体带的特性进行了讨论 The high-spin structure of 138Ce was studied by heavy ion fusion-evaporative reaction 124Sn (18O, 4n) 138Ce. The experiment was performed on the H-13 tandem accelerator of China Institute of Atomic Energy. The energy of the beam was 78 MeV. After the analysis of the γγ coincidence and the directional correlation ratio DCO, a new 138Ce high spin state energy level graph was established and two flat ellipses Deformation of the collective rotation zone, and the characteristics of this flat elliptic collective zone were discussed 
