Abstract

The collisional broadening and shift rate coefficients of the 283.39 nm (6p23P0 → 7s3P 1 o ), 364.06 nm (6p23P1 → 7s3P 1 o ), 368.45 nm (6p23P1 → 7s3P 0 o ) and 405.90 nm (6p23P2 → 7s3P 1 o ) Pb lines by He and Ar have been measured by fitting the experimental absorption line shapes to theoretical Voigt profiles. The absorption measurements were performed in a resistively heated, Pb loaded oven with an integrated dc noble gas discharge to produce also Pb atoms in the 6p23P1 and 6p23P2 metastable states. The diffusion of the metastable atoms out of the discharge zone into the neutral noble-gas atmosphere enabled the line-shape and shift measurement of the lines involving the metastable states without the influence of the discharge plasma.
