Spectral Properties of N6+, Ne9+, and Al12+ Ions in Dense Plasma
The influence of the dense plasma environment on the energy levels and transition rates of H-like N6+, Ne9+, and Al12+ ions have been examined. The structural and spectral properties have been analyzed by employing the relativistic configuration interaction (RCI) technique using the ion sphere model as the modified interactive potential between the nucleus and the electron. It is observed that for every transition, the transition energies are red shifted. The plasma screening effect on weighted oscillator strengths has also been examined. Additionally, the ground state thermodynamic pressure within the ion sphere and the radial wavefunctions of the spectral electron for the various states of N6+, Ne9+, and Al12+ ions at plasma density 1 × 1023 cm–3 were also studied. The line intensity ratio has also been computed for the first two spectral lines: [1s1/2 – 2p3/2 (1–3)] and [1s1/2 – 2p1/2 (1–2)]. Our computed data exhibits a good quantitative agreement with the other results reported in the literature as well as with the experimental results reported in the National Institute of Science and Technology (NIST) database. The current findings will be helpful in laboratory and astrophysical plasma modelling and characterization of hot dense plasma.
期刊介绍:
Journal of Experimental and Theoretical Physics is one of the most influential physics research journals. Originally based on Russia, this international journal now welcomes manuscripts from all countries in the English or Russian language. It publishes original papers on fundamental theoretical and experimental research in all fields of physics: from solids and liquids to elementary particles and astrophysics.
