Notes. Our measured Pb IV and Pb V Stark FWHM (Wm in pm with estimated accuracies) at given T (in 104 K ± 14%) normalized to an N = 1 × 1023 m-3. The symbols ∗ and ∗ ∗ denote wavelengths taken from NIST (2010) and Crawford et al. (1937), respectively. Wth represents theoretical FWHM values presented by Alonso-Medina et al. (2010) except for the four Pb IV wavelengths from Table 2, where the Wth denotes the resulting Stark widths (Res. Wth) of superposition (see Table 2). Transitions are taken from Crawford et al. (1937) and Gutmann (1969).
