First evaluations of the blackbody-radiation (BBR)-induced shift and broadening of highly excited Rydberg states were based on the account of only the first term of the expansion for the Planck’s distribution in powers of the ratio of the BBR-photon energy to the environmental thermal energy. The corresponding asymptotic expression for the shift is proportional to a sum rule for the oscillator strengths, which is identical for all states, independently of their principal and angular-momentum quantum numbers. The broadening appeared proportional to the sum of the oscillator-strength first moments, which is dependent on only the principal quantum number, being independent of the state’s angular momentum. In this article, we demonstrate that the account of higher-order terms of the Planck’s distribution expansion provides corrections revealing the dependence of asymptotic shift and broadening on the Rydberg-state principal and angular-momentum quantum numbers. The strongest correct...

使用振荡器强度和规则评估黑体辐射引起的里德堡能级变宽和位移的角动量依赖性

对黑体辐射(BBR)引起的高激发Rydberg态的位移和展宽的初步评估仅基于普朗克分布的扩展的第一项,即BBR光子能量与光子能量之比的幂。环境热能。位移的相应渐近表达式与振荡器强度的求和规则成正比,对于所有状态而言,其总和是相同的,而与它们的本征和角动量量子数无关。展宽的出现与振荡器强度一阶矩之和成比例,该矩仅取决于主量子数,而与状态角动量无关。在这篇文章中,我们证明了对普朗克分布展开的高阶项的解释提供了更正,从而揭示了渐近位移的依赖性,并拓宽了里德堡状态的本原和角动量的量子数。最强的正确...
