“…In particular, ABAKO works using a set of analytical potentials developed by us, which can model both isolated ions (Martel et al, 1995) and ions immersed into plasmas (Gil et al, 2002), including plasma effects (such as the continuum lowering of the ionization potential and the shift on the energy levels, total energies and wave functions), and single and core excited configurations . Moreover, in this case, in order to avoid the iterative procedures of the self-consistent models, the atomic magnitudes are evaluated using central analytical potentials, within the framework of the independent particle model, which have demonstrated to be an interesting and useful option to work out accurate ionic populations, and average ionizations in a wide range of densities and temperatures.…”

In this work is accomplished the determination of the corona, local and non-local thermodynamic equilibrium regimes for optically thin carbon plasmas in steady state, in terms of the plasma density and temperature using the ABAKO code. The determination is made through the analysis of the plasma average ionization and ion and level populations. The results are compared whit those obtained applying Griem's criterion. Finally, it is made a brief analysis of the effects of the calculation of level populations assuming different plasma regimes in radiative properties, such as emissivities and opacities.

[25] It is important to mention here that we set the same values of the parameters B and C in the model potentials for the free-atomic systems and the screening environments as recommended in the earlier studies. [38,39,42,43] To represent the correlation effect between the electron, positron and the core, we consider the Hylleraas-type basis functions in the form of [44][45][46] r l i 1 r m i 2 r n i 12 e −α(r 1 +r 2 ) :…”

S-wave resonances of positron-helium and positron-lithium systems in kappa-distribution plasmas are investigated using Hylleraas-type wave functions in the framework of the stabilization method. A model potential approach is used to represent the interactions between the outer electron, the positron and the core. The resonance parameters (position and width) of positron-helium and positron-lithium systems below the Ps(2s) threshold are reported as a function of screening parameter and spectral index of plasma.

“…On the other hand, for lowly ionized intermediate and high-Z plasmas this detailed calculation becomes impracticable and a detailed relativistic configuration accounting approach is chosen. In particular, ABAKO works using a set of analytical potentials developed by us which can model both isolated ions [6] and ions immersed into plasmas [7] including plasma effects and single and core excited configurations [8]. Even for situations wherein more celerity is desired, the code can perform the atomic calculations using a relativistic screened hydrogenic model [9].…”
