Rates of the blackbody radiation-induced excitation and decay were calculated for the S-, P-, D-series of the Rydberg states in sodium atoms with the Fues model potential method. Comparisons between three branches of the state depopulation mechanism (spontaneous decays, blakbody radiation-induced and excitations) were carried out. Simple analytical formulas were proposed for ratios of the blackbody radiation-induced decay and excitation rates to the spontaneous decay rate. [ABSTRACT FROM AUTHOR]

The rates of excitations and decays induced by blackbody radiation were calculated in the single-electron Fues' model potential approach for states up to n = 100 in rubidium s-, p- and d-series. On the basis of the calculations, general regularities for maxima rates of blackbody radiation induced decays and excitations were ascertained and a simple polynomial-based approximation formula was proposed for blackbody radiation induced decay and excitation rates of Rydberg states. A temperature parameterization for T = 50-1500 K was also proposed and respective matrices of coefficients were calculated. [ABSTRACT FROM AUTHOR]
