Transition probabilities of 30 Pb II lines of the spectrum obtained by emission of a laser-produced plasma

Transition probabilities have been determined for 30 lines of Pb II measuring the intensities of the emission lines of a laser-produced plasma (LPP) of Pb in an atmosphere of Ar. The plasma has been seen to contain local thermodynamic equilibrium (LTE) and homogeneity; the plasma studied has a temperature of 11 500 K and an electron density of 1016 cm-3. The experimental results obtained during this study have been compared with the experimental and theoretical values given by other authors. (orig.)
