We introduce a two-particle, two-hole mixed configuration scheme to fit $E2$ strengths for the $0\leftrightarrow 2, 2\leftrightarrow 4$, and $4\leftrightarrow 6$ transitions in ${}^{194}\mathrm{Pt}$. The interaction includes two sets of pairing operators, {$S^{\pm }\left(t\right),S^0\left(t\right)$} $(t=s,d)$. Solutions within this framework are used to analyze energy spectra, $E2$ transitions, and band-mixing features of the model. The results confirm that mixing is small and similar for $J=2$, 4, and 6, with the calculated energies and transition matrix elements in excellent agreement with experimental data.

Pt194中的核结构和能带混合

我们引入了两粒子两孔混合配置方案以适合 $Ë2$ 的优势 $0\leftrightarrow 2， 2\leftrightarrow 4$， 和 $4\leftrightarrow 6$ 过渡 ${}^{194}铂$。互动包括两组配对运算符，{${\mathrm{小号}}^{\pm }（Ť），{\mathrm{小号}}^0（Ť）$} $（Ť=s，d）$。该框架内的解决方案用于分析能谱，$Ë2$过渡和模型的频段混合功能。结果确认混合很小$Ĵ=2$，4和6，计算出的能量和跃迁矩阵元素与实验数据非常吻合。
