论文摘要
通过使用广义相对论的伪能力模型，在多参考Fock空间耦合群集方法的框架中对碳一氧化碳的Cameron系统进行了计算研究，用于有效引入全电子校正治疗的相对性。计算了极弱$ a^3π_{ω= 0^+，1} - x^1σ^+$过渡概率和亚稳态$ a^3π$状态的辐射寿命和辐射寿命。精细结构常数$α= e^2/\ hbar c $对卡梅隆系统过渡强度的可疑变化的影响也得到了数值评估。
The intercombination $a^3Π- X^1Σ^+$ Cameron system of carbon monoxide has been computationally studied in the framework of multi-reference Fock space coupled cluster method with the use of generalized relativistic pseudopotential model for the effective introducing the relativity in all-electron correlation treatment. The extremely weak $a^3Π_{Ω=0^+,1} - X^1Σ^+$ transition probabilities and radiative lifetimes of the metastable $a^3Π$ state were calculated and compared with their previous theoretical and experimental counterparts. The impact of a presumable variation of the fine structure constant $α=e^2/\hbar c$ on transition strength of the Cameron system has been numerically evaluated as well.
