Abstract

Relativistic multichannel theory has been used to calculate the even-parity Rydberg states and odd-parity autoionizing (AI) Rydberg spectrum converging to the limit of second and third excited core states of selenium (Se), taking into account the ionic core dipole polarization effect caused by the Rydberg electron. Six even-parity Rydberg series $4s^{2}4p^3({}^4{S}^o)n{p}^3{P}_{0,1,2}$ and $4s^{2}4p^3({}^4{S}^o)n{p}^5{P}_{1,2,3}$ are calculated, along with AI Rydberg states converging to $4s^{2}4p^3({}^2{D}_{3/2}^o)$ or $4s^{2}4p^3({}^2{D}_{5/2}^o)$ in $J^{\pi }={(1)}^{-},{(2)}^{-}$ or ${(3)}^{-}$ symmetry. In general, there is less than a 0.05 difference between calculated and experimental quantum defects. The influence of the perturbers on quantum defects and peak profiles has all been investigated. The accuracy of our calculations allows us to provide a reliable the assignment of the measured AI Rydberg states and the accompanying total angular momentum.

摘要

相对论多通道理论已用于计算偶宇称里德堡态和奇宇称自电离 (AI) 里德堡光谱收敛到硒 (Se) 的第二和第三激发核态的极限，同时考虑离子核偶极极化效应由里德堡电子引起。六个偶宇称里德堡级数$\mathrm{4个}{秒}^{\mathrm{2个}}\mathrm{4个}{p}^{\mathrm{3个}}({的}^{\mathrm{4个}}{\mathrm{小号}}^o)n{p}^{\mathrm{3个}}{P}_{0,\mathrm{1个},\mathrm{2个}}$和$\mathrm{4个}{秒}^{\mathrm{2个}}\mathrm{4个}{p}^{\mathrm{3个}}({的}^{\mathrm{4个}}{\mathrm{小号}}^o)n{p}^{\mathrm{5个}}{P}_{\mathrm{1个},\mathrm{2个},\mathrm{3个}}$被计算出来，连同 AI 里德堡状态收敛到$\mathrm{4个}{秒}^{\mathrm{2个}}\mathrm{4个}{p}^{\mathrm{3个}}({的}^{\mathrm{2个}}{丁}_{\mathrm{3个}/\mathrm{2个}}^o)$或者$\mathrm{4个}{秒}^{\mathrm{2个}}\mathrm{4个}{p}^{\mathrm{3个}}({的}^{\mathrm{2个}}{丁}_{\mathrm{5个}/\mathrm{2个}}^o)$在${杰}^{\pi }={(\mathrm{1个})}^{-},{(\mathrm{2个})}^{-}$或者${(\mathrm{3个})}^{-}$对称。通常，计算的和实验的量子缺陷之间的差异小于 0.05。扰动器对量子缺陷和峰分布的影响都已得到研究。我们计算的准确性使我们能够可靠地分配测得的 AI 里德伯态和伴随的总角动量。
