摘要/Abstract

摘要： Energy levels, wavefunction compositions and lifetimes have been computed for all levels of 1s²2s²2p⁵, 1s²2s2p⁶, 1s²2s²2p⁴3s, 1s²2s²2p⁴3p, and 1s²2s²2p⁴3d configurations in highly charged F-like tungsten ion. The multiconfigurational Dirac-Fock method (MCDF) is adopted to generate the wavefunctions. We have also presented the transition wavelengths, oscillator strengths, transition probabilities, and line strengths for the electric dipole (E1) and magnetic quadrupole (M2) transition from the 1s²2s²2p⁵ ground configuration. We have performed parallel calculations with the flexible atomic code (FAC) for comparing the atomic data. The reliability of present data is assessed by comparison with other theoretical and experimental data available in the literature. Good agreement is found between our results and those obtained using different approaches confirm the quality of our results. Additionally, we have predicted some new atomic data for F-like W that were not available so far and may be important for plasma diagnostic analysis in fusion plasma.
