Energy levels and spectral lines of Ne VII (original) (raw)

Atomic data for Ne-like ions useful in Plasma Diagnostic

Canadian Journal of Physics

Motived by the recent measurement of transition lines for Ne-like Hf and W, we have reported atomic data in the form of multiconfiguration Dirac–Fock transition energies and wavefunction compositions of 209 levels belonging to the configurations 2s22p6, 2s22p5ns (n = 3, 4, 5, 6, 7), 2s22p5np (n = 3, 4, 5, 6, 7), 2s22p5nd (n = 3, 4, 5, 6, 7), 2s22p5nf (n = 4, 5), 2s22p55g, 2s2p6ns (n = 3, 4, 5), 2s2p6np (n = 3, 4, 5), 2s2p6nd (n = 3, 4, 5), 2s2p6nf (n = 4, 5), and 2s2p65g of Hf LXIII, Ta LXIV, W LXV, and Re LXVI. Radiative rates, oscillator strengths, transition wavelengths, and line strengths have been calculated for ground state electric dipole (E1) transition among these levels. These values were obtained using GRASP (general-purpose relativistic atomic structure package) code, which includes Breit and QED effects along with Dirac–Fock potential and second-order Coulomb interaction. We have compared our results with the data compiled using FAC (flexible atomic code) and also with ...

Quantum‐mechanical Calculations of Ne VII Spectral Line Widths

2007

We present in this paper quantum-mechanical calculations for the electron impact Stark linewidths of the 2s3s-2s3p transitions for the beryllium-like neon. Calculations are made in the frame of the impact approximation and for intermediate coupling, taking into account fine structure effects. A comparison between our calculations and experimental and other theoretical results showed a good agreement. This is the first time that we find such a good agreement between quantum and experimental linewidths of highly charged ions.
