All Tables

Table 1: MCDF calculated energy levels relative to the ground energy of Fe XX with spectroscopic identifications. The leading percentage compositions of levels which contributions exceed 10% are presented in the last column.
Table 2: CITRO calculated energy levels relative to the ground energy of Fe XX with spectroscopic identifications. The leading percentage compositions of levels which contributions exceed 10% are presented in the last column.
Table 3: Comparison of calculated energies for Fe XX levels with data compiled by NIST ( $E^{{\rm NIST}}$ ). $E^{{\rm SS}}$ - energies calculated by Mason & Bhatia (1983) with SUPERSTRUCTURE, $E^{{\rm BPRM}}$ - values obtained by Nahar (2004) with Breit-Pauli R-matrix code, $E^{{\rm GRASP}}$ and $E^{{\rm CITRO}}$ - our values. Indexes of levels in the first column and CSFs in the second column are taken from Table 1. Energies are in cm^-1.
Table 4: Estimation of contribution spin-orbit (s-o), spin-other-orbit (s-o-o), spin-spin (s-s) and orbit-orbit (o-o) within shell interactions to energies for Fe XX levels within n=2 complex. $E_1=E^{{\rm s-o}}$ , $E_2=E^{{\rm s-o}}+E^{{\rm s-o-o}}$ , $E_3=E^{{\rm s-o}}+E^{{\rm s-o-o}}+E^{{\rm s-s}}$ and $E_4=E^{{\rm s-o}}+E^{{\rm s-o-o}}+E^{{\rm s-s}}+E^{{\rm o-o}}$ .
Table 5: Suggested change of spectroscopic identifications of levels to ensure the completeness of spectroscopic dataset. The indexes of levels for which spectroscopic identifications are changed are presented in the first column. The second column contains index of level with the same highest contribution of configuration state function (Table 1) as level from the first column before change. Indexes of levels in the first two columns are taken from Table 1.
Table 6: Comparison of calculated Fe XX wavelengths $\lambda$ and line strengths S with values presented by NIST. BPRM - data from Nahar (2004), GRASP and CITRO - our values. Indexes of levels in the first two columns are taken from Table 1.
Table 7: The five major spontaneous radiative transition probabilities A^r and total transition probabilities $\sum A^r$ for each level. Arrow marks the final level to which radiative transition happens from the level. The sum of all radiative probabilities from the corresponding level is given in the last column.
