“…In Table 3 we compare our energies with the grasp and fac codes for the levels of the 3s 2 3p 4 4d configuration with those of NIST and CIV3 [19]. As for other levels, agreement between our GRASP1 and NIST energies is satisfactory, but these are underestimated by up to 0.25 Ryd, because of the inclusion of limited CI.…”

“…For levels of the 3s 2 3p 4 4p configuration, the only results available for comparison are those of Mohan et al [19] from the CIV3 code. Their energies agree closely with our GRASP1 calculations, but are underestimated by up to 0.25 Ryd in comparison with our more elaborate GRASP3 and FAC1/FAC2 results, perhaps for the same reason as for the levels of the 3s 2 3p 4 4s configuration.…”

“…However, their reported results are limited to only a few levels/transitions and hence are insufficient for plasma modelling. Finally, Mohan et al [19] have performed a comparatively larger calculation, as they have also included 57 levels of the 3s 2 3p 4 4s, 3s 2 3p 4 4p and 3s 2 3p 4 4d configurations, apart from the lowest 31 levels of the 3s 2 3p 5 , 3s3p 6 and 3s 2 3p 4 3d configurations. Furthermore, they have included an extensive CI (see Table 3 of [19]) for the construction of wavefunctions, apart from one-body relativistic operators in the Breit-Pauli approximation.…”

We report on calculations of energy levels, radiative rates, oscillator strengths, and line strengths for transitions among the lowest 253 levels of the (1s 2 2s 2 2p 6 ) 3s 2 3p 5 , 3s3p 6 , 3s 2 3p 4 3d, 3s3p 5 3d, 3s 2 3p 3 3d 2 , 3s 2 3p 4 4s, 3s 2 3p 4 4p and 3s 2 3p 4 4d configurations of Ti VI. The general-purpose relativistic atomic structure package (grasp) and flexible atomic code (fac) are adopted for the calculations. Radiative rates, oscillator strengths and line strengths are reported for all electric dipole (E1), magnetic dipole (M1), electric quadrupole (E2) and magnetic quadrupole (M2) transitions among the 253 levels, although calculations have been performed for a much larger number of levels. Comparisons are made with existing available results and the accuracy of the data is assessed. Additionally, lifetimes for all 253 levels are listed, although comparisons with other theoretical results are limited to only 88 levels. Our energy levels are estimated to be accurate to better than 1% (within 0.03 Ryd), whereas results for other parameters are probably accurate to better than 20%. A reassessment of the energy level data on the NIST website for Ti VI is suggested.

“…Recently the atomic structure calculations for multi-electron ions have received a great deal of attention both experimentally and theoretically due to their importance in fusion plasmas and astrophysics [1][2][3][4]. The Al-like ions are of much importance because the aluminum isoelectronic sequence has three valence electrons outside a closed n = 2 core, and provide a model for studying effects of strong correlation on closely spaced levels in heavy atoms [5].…”

“…However, the available lifetime data for Ar II differ by much more than their error bars from each other and by large factors from computations available at the time (see plots in a study geared towards low charge states [235]). A single (beam-foil) lifetime value exists also for Ti VI [241], which was followed 26 years later by a single-element computation [242]). Meanwhile a further beam-foil data point for K III has been added by H. P. Garnir at Liège (τ = 2.08 ± 0.2 ns) [243].…”

The interpretation of atomic observations by theory and the testing of computational predictions by experiment are interactive processes. It is necessary to gain experience with "the other side" before claims of achievement can be validated and judged. The discussion covers some general problems in the field as well as many specific examples, mostly organized by isoelectronic sequence, of what level of accuracy recently has been reached or which atomic structure or level lifetime problem needs more attention.
