通过1 3 0 Te(1 6O ,5nγ) 1 4 1 Nd反应布居了1 4 1 Nd的高自旋态能级 .对反应产生的在束γ射线进行了γ射线单谱和γ -γ符合测量 .建立了激发能达 76 1 4 .5keV的1 4 1 Nd能级纲图 ,新发现了 1 2条γ射线和 1 5个能级 .基于实验测量的γ跃迁各向异性 ,建议了1 4 1 Nd部分能级的自旋值 .用一个h1 1 2 价中子空穴与1 4 2 Nd核芯晕态的耦合可以定性地解释1 4 1 Nd的能级结构 The high spin state energy of 1 4 1 Nd was settled by the reaction of 1 3 0 Te (1 6O, 5nγ) 1 4 1 Nd.γ-ray coincidence measurements were performed on γ-rays in the beam. A 1 4 1 Nd level diagram with an excitation energy of 76 1 4.5keV was established and 12 new γ-rays and 15 energy levels were newly discovered.Based on the experimentally measured γ-transition anisotropy, it is proposed that 1 4 1 The spin value of the Nd partial energy level. The coupling of a h1 1 2 valence hole with a 1 4 2 Nd core can qualitatively explain the energy structure of 1 4 1 Nd
