Abstract A statistical method is introduced to deal with the two-electron energies of a configuration in the detailed term accounting (DTA) approximation for the spectral line absorption in the radiative opacity of laser-produced plasmas in local thermodynamics equilibrium. The relativistic Hartree-Fock-Slater self-consistent field average atom model is used to select the reference ion with most-probability and providing basically atomic data. In this way, fully frequency-dependent and spectral resolved opacity for heavy element can be obtained readily for the primary design of radiation transfer in the inertial confinement fusion simulation. Opacities of Au plasmas are given.
