Abstract

Strengths and Stark widths of the prominent visible PbI and PbII lines are measured in emission by means of a gas-driven shock tube. Absolute ionic line strengths for $7 s - 7 p$ and $7 p - 7 d$ arrays conform well to quantum-mechanical sum rules and agree with theoretical predictions, but $6 d - 5 f$ results differ markedly from central-field approximations. Neutral-line strengths agree satisfactorily with available comparison data. Semiempirical theory predicts the widths of PbII lines with characteristic reliability of better than 25%.
