通过对２５２Ｃｆ自发裂变产生的瞬发γ谱的测量，对丰中子奇Ａ核１４５，１４７Ｃｅ的高自旋态进行了研究，首次识别了１４５Ｃｅ的集体带结构，扩展了１４７Ｃｅ的集体带结构，扩展了１４７Ｃｅ的能级，并新识别了３个边带，粒子－转子模型的计算指出，１４５，１４７Ｃｅ的晕带可能来自于νｉ１３／２轨道的耦合，１４５Ｃｅ基态起源于（νｈ９／２νｆ７／２）组态混合，而１４７Ｃｅ基态则起源于νｈ９／２轨道．在这两个核中未观测到明显的八极形变带，然而，在１４７Ｃｅ中观测到的一个边带，可能显露出八极关联的迹象．

The N-terminal eF-hand calcium-binding proteins 1–3(NeCAB1–3) constitute a family of predominantly neuronal proteins characterized by the presence of at least one eF-hand calcium-binding domain and a functionally less well characterized C-terminal antibiotic biosynthesis monooxygenase domain. All three family members were initially discovered due to their interactions with other proteins. NeCAB1 associates with synaptotagmin-1, a critical neuronal protein involved in membrane trafficking and synaptic vesicle exocytosis. NeCAB2 interacts with predominantly striatal G-protein-coupled receptors, while NeCAB3 partners with amyloid-β A4 precursor protein-binding family A members 2 and 3, key regulators of amyloid-β production. This demonstrates the capacity of the family for interactions with various classes of proteins. NeCAB proteins exhibit distinct subcellular localizations: NeCAB1 is found in the nucleus and cytosol, NeCAB2 resides in endosomes and the plasma membrane, and NeCAB3 is present in the endoplasmic reticulum and Golgi apparatus. The antibiotic biosynthesis monooxygenase domain, an evolutionarily ancient component, is akin to atypical heme oxygenases in prokaryotes but is not wellcharacterized in vertebrates. Prokaryotic antibiotic biosynthesis monooxygenase domains typically form dimers, suggesting that calcium-mediated conformational changes in NeCAB proteins may induce antibiotic biosynthesis monooxygenase domain dimerization, potentially activating some enzymatic properties. However, the substrate for this enzymatic activity remains uncertain. Alternatively, calcium-mediated conformational changes might influence protein interactions or the subcellular localization of NeCAB proteins by controlling the availability of protein–protein interaction domains situated between the eF hands and the antibiotic biosynthesis monooxygenase domain. This review summarizes what is known about genomic organization, tissue expression, intracellular localization, interac
