摘要

本文利用相互作用玻色子模型-3 （IBM-3）研究了偶偶氪同位素的量子相变。利用仿射SU（1,1）代数方法探讨了U(5)和O(6)对称极限之间的过渡区域。结合同位旋自由度构造了哈密顿算符，并用Bethe-Ansatz方法求解。得到了所选同位素的理论能谱，并与实验数据进行了比较。此外，根据已知的测量结果，计算并评估了电四极跃迁概率B（E2）。我们的结果与实验值一致，验证了IBM-3和仿射代数在模拟轻核中的适用性。

Exploring algebraic symmetries in krypton nuclei

This study investigates the quantum phase transition in even-even Krypton isotopes using the Interacting Boson Model-3 (IBM-3). The transitional region between U(5) and O(6) symmetry limits is explored using an algebraic approach based on the affine SU(1,1) algebra. The Hamiltonian is constructed incorporating isospin degrees of freedom and solved using the Bethe-Ansatz method. Theoretical energy spectra are obtained and compared to experimental data for selected isotopes. Additionally, the electric quadrupole transition probabilities B(E2) are calculated and evaluated against known measurements. Our results agree with experimental values, validating the applicability of IBM-3 and affine algebra in modeling light nuclei.
