Studies of the M1–E2 interference effect in the Zeeman spectra of two mixed-type forbidden lines, 733.2 nm of Pb I and 710.2 nm of Pb II, are reported. In the experiment, the odd isotope 207 of Pb was used. By the use of computer modelling techniques the simulated contours were fitted to the recorded spectra in order to determine the electric-quadrupole admixture in forbidden lines. The E2 admixtures found are (4.12 ± 0.07)% for the 733.2 nm line and (4.25 ± 0.18)% for the 710.2 nm line of Pb II. Our results are compared with recent theories and other experiments.

“…2 shows, these transitions violate the electrodipole forbiddenness, a parity selection rule. Radiative lifetimes of 6p 2 (3/2,3/2)0,2 levelsthe upper levels for these transitionshave been determined by us using data from [8]. The respective values are τ = 9.73 ms for the level with J = 0 and τ = 38.2 ms for the level with J = 2.…”

Excitation of even levels of lead atoms was studied using the method of extended crossing beams with recording of optical signal emitted by excited atoms. Fortyeight excitation cross sections have been measured at an incident electron energy of 50 eV. Four optical excitation functions (OEFs) have been recorded under varying electron energies in the range E = 0-200 eV. The cross-sections obtained have been used to examination of empirical regularities in the behavior of excitation cross-sections, including those of perturbed series.

“…An analysis of the energy-levels in the 6p 2 and 6p 7p configurations performed by Gil and Heldt [18] including configuration interaction effects, can serve as an estimate of the configuration mixing. In their article they obtained two sets of eigenvectors, denoted "Version I" and "Version II" (Table 4).…”
