Solutions of the nonrelativistic Hartree-Fock equations for 3P and 1P terms of the np5(n+1)s configurations and for the center of gravity of the np5nd configurations of krypton (n=4) and xenon (n=5) 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.
