摘要：

The “forbidden” Pb 6p23P 0↦6p23P1 line at 1278.9 nm is measured by diode laser absorption in a resistively heated hot-pipe filled with a lead vapour and argon as buffer gas. The measurements performed at a temperature of 1170 K and a lead number density of 2.4×1015 cm-3 yield the oscillator strength fF = (4.5±1.1)×10-7 which corresponds to a radiative transition probability AF = (6.1±1.5) s-1. Within the error bars, the result is in agreement with theoretical data published by different authors.
