AI总结:

本文建立 proxy-SU(3) 对称性与球壳模型的对应关系,证明其本质是用 de Shalit-Goldhaber 伙伴轨道替代闯入轨道,并在 Nilsson 模型中得到一致验证。

摘要:

Proxy-SU(3) 对称性是一种近似方案,它将 sd 壳的 Elliott SU(3) 代数扩展到更重的壳。该近似在2017年提出时,曾通过 Nilsson 模型中进行的计算得到论证。最近,我们的研究组成功将 Elliott SU(3) 模型的笛卡尔基映射到球壳模型基,证明了 proxy-SU(3) 近似对应于用闯入轨道的 de Shalit-Goldhaber 伙伴轨道替代这些闯入轨道,从而为在壳模型计算中使用 proxy-SU(3) 近似铺平了道路。proxy-SU(3) 方案与球壳模型之间的联系也已在 Nilsson 模型的原始框架中得到推导,并取得了相同结果。

英文摘要:

Proxy-SU(3) symmetry is an approximation scheme extending the Elliott SU(3) algebra of the sd shell to heavier shells. When introduced in 2017, the approximation had been justified by calculations carried out within the Nilsson model. Recently our group managed to map the cartesian basis of the Elliott SU(3) model onto the spherical shell model basis, proving that the proxy-SU(3) approximation corresponds to the replacement of the intruder orbitals by their de Shalit-Goldhaber partners, paving the way for using the proxy-SU(3) approximation in shell model calculations. The connection between the proxy-SU(3) scheme and the spherical shell model has also been worked out in the original framework of the Nilsson model, with identical results.
