Atomic Structures and Radiative Properties of He-like Ions in Debye Plasmas

摘要

A detailed investigation of plasma screening effects on atomic structure and transitionproperties are presented for He-like ions embedded in dense plasma environment. MulticonfigurationDirac-Fock calculations were carried out for these ions by considering a Debye-Hiickelpotential. A large-scale relativistic configuration-interaction method is adopted to calculate transitionenergies and transition probabilities and to allow for a systematic improvement of thecalculations. Comparison of the presently calculated results with others, when available, is made.
