摘要: Abstract In this paper, we propose two kinds of theoretical methods: (i) a self-consistent fully relativistic model, Flexible Atomic Code (FAC) and (ii) an analytical form based on the tensor expression Breit-Pauli Hamiltonian, for describing electronic structure highly charged ions under external confinement. The effect confinement due to Debye plasma is incorporated through standard Debye-Huckel potential, yet that quantum treated exponential cosine screened Coulomb potential. For latter corrections arise from mass Darwin are derived. As test case, effects produced by above plasmas energies transition rates H-like Mg11+ Fe25+ investigated. Some characteristics respective properties in regard shielding strength analyzed. present results compared with each other available values same system, show good quantitative agreement.
