摘要
通过在束γ谱的实验研究,建立了^(153)Dy的非常高的自旋态的能级图,最高自旋态为81/2.所用核反应为^(122)Sn(^(36)s,5n),束流能量165MeV.在同质异能态(I=47/2)以上,能级结构展示出极端复杂的单粒子跃迁特性.对缺中子Dy核的形状随中子数N及自旋态I变化的系统性进行了讨论.
The ^(153)Dy level structure has been investigated through in-beam γ-ray spectroscopy experiment. The reaction ^(122)Sn (^(36)S, 5n) was studied at beam energy 165MeV. The highest spin was 81/2. Above I=47/2 isomer, extremely complicated single-particle character was shown. Nuclear shape changes with N and I in the neutron-deficient Dy nuclei were discussed.
