Excited-State Wave Functions, Excitation Energies, and Oscillator Strengths for Krypton and Xenon

Solutions of the nonrelativistic Hartree-Fock equations for ${}_{}{}^3{}_{}{}^{}P$ and ${}_{}{}^1{}_{}{}^{}P$ terms of the $n{p}^5\mathrm{}(n+1\mathrm{})s$ configurations and for the center of gravity of the $n{p}^5\mathrm{nd}$ configurations of krypton ($n=4\mathrm{}$) and xenon ($n=5\mathrm{}$) have been obtained. Wave functions are tabulated and results of computations of excitation energies and oscillator strengths are presented. For krypton, the computed oscillator strengths of the 1165-Å and 1236-Å lines are 0.136 and 0.138, and for xenon those of the 1296-Å and 1470-Å lines are 0.147 and 0.194, respectively. Calculated values of various parameters such as spin-orbit interaction and excitation energies compare satisfactorily with experimental values. The adequacy of the nonrelativistic Hartree-Fock approximation is discussed.
