Abstract
The atomic spectral properties of the Li-like Al XI ion embedded in dense plasma environment have been investigated under the combined effects of external electric and magnetic fields. For this purpose, relativistic configuration interaction (RCI) method is employed, incorporating an analytical b-potential along with the electric and magnetic fields. We studied the plasma screening effect on binding energy and transition energy of the low-lying transitions 2s 2S1/2 → 2p 2P1/2,3/2 of Al XI ion. We have also analysed the effect of electric field and plasma screening on the excitation energy levels. Additionally, we investigated plasma screening effect, along with external electric and magnetic fields on the transition probability of different states corresponding to transitions 2s 2S1/2 (± 1/2) → 2p 2P1/2 (± 1/2), 2s 2S1/2 (± 1/2) → 2p 2P3/2 (± 3/2, ± 1/2). Our computed results show good agreement with the energy values available at the National Institute of Standards and Technology (NIST) database.
