Abstract A fully relativistic configuration interaction method is developed to investigate the transition energies and general oscillator strengths of the lower lying states of krypton, for both optically allowed and optically forbidden transitions. The calculated results are in agreement with the recent experimental measurements. The calculated transition energies for the 5s and 5s' transitions are 9.970 and 10.717eV, which agree with the experimental data of 10.033 and 10.643eV. The calculated oscillator strengths are 0.211 and 0.170, comparable with the experimental results 0.214 (±0.012) and 0.194 (±0.012), respectively. The momentum transfer positions (K2 in a.u.) of the minimum and maximum GOSs in the 4s24p6→o 4s2 4p5 (5s+5s') transitions are 1.105 and 2.225, comparable with the measurements results 1.24 and 2.97 [Phys. Rev. A 67 (2003) 062708].
