采用约束反对称分子动力学方法结合生成元坐标法研究了B中的激发态结构。在正宇称态和负宇称态中提出了具有发达簇核结构的各种激发态。对于负宇称态，我们建议采用具有簇结构的能带。该谱带从状态开始，可以与最近观察到的实验谱带相对应。在正宇称状态下，发现了具有周围核子的双核簇结构。 Aband 被认为是由具有大扁长形变形的非常发达的团簇结构构成的。我们讨论了与 Be 分子轨道结构相关的簇结构特征。
Structures of excited states inB are investigated with a method of-constraint antisymmetrized molecular dynamics in combination with the generator coordinate method. Various excited states with developed cluster core structures are suggested in positive- and negative-parity states. For negative-parity states, we suggest a band with acluster structure. This band starts from thestate and can correspond to the experimental band observed recently. In positive-parity states, twocore cluster structures with surrounding nucleons are found. Aband is suggested to be constructed from a remarkably developed cluster structure with a large prolate deformation. We discuss features of the cluster structure in association with molecular orbital structures ofBe.
