Comparisons of log(gf) from the present work (black horizontal line) with the experimental ones (NIST) and previous works: W07 refers to Witthoeft et al. (2007), R15 refers to Radžiūtė et al. (2015), W16 refers to Wang et al. (2016), D12 refers to Dong et al. (2012), W18 refers to Wang et al. (2018), L10 refers to Ludlow et al. (2010), L11 refers to Liang et al. (2011), T12 refers to Tayal (2012), and T07 refers to Tayal (2007). We note that this comparison is limited to relatively strong transitions with log(gf) ≳ 10⁻⁶ originating from the lowest five energy levels.
