摘要

将核聚类的辛对称方法推广到更一般的多簇核系统。在A1=A2=…=Ak=4的极限情况下，我们得到了各种各样的多α-粒子簇模型的SSAC内的微观对应。作为一个例子，新的显微方法应用于16O的4α团簇核体系。用实验很好地描述了16O中最低Kπ=01+、Kπ=02+、Kπ=01−、Kπ=21+、Kπ=31−和Kπ=11−带的激发态，以及实验已知的不使用有效电荷的B（E2）低能跃迁。

Symplectic symmetry approach to multicluster nuclear systems: The case of 16O

Symplectic symmetry approach to clustering (SSAC) in the atomic nucleus is generalized for the more general multicluster nuclear systems. In the limiting case when

A_{1} = A_{2} = \dots = A_{k} = 4

one obtains a microscopic counterpart within the SSAC of the wide class of various multi-α-particle cluster models. As an example, the new microscopic approach is applied to the 4α cluster nuclear system of ¹⁶O. A good description for the excited states in the lowest

K^{π} = 0_{1}^{+}

K^{π} = 0_{2}^{+}

K^{π} = 0_{1}^{-}

K^{π} = 2_{1}^{+}

K^{π} = 3_{1}^{-}

and

K^{π} = 1_{1}^{-}

bands in ¹⁶O with experiment, as well as for the experimentally known

B (E 2)

low-energy transitions without the use of an effective charge, is obtained.
