The neutron capture cross sections of 204Pb and 206Pb have been measured at the CERN n_TOF installation using the time of flight method with the pulse height weighting technique. In a preliminary analysis of 204Pb we have determined by first time the capture cross sections for two strong s-wave resonances below 2.5 keV, which seem to enhance the Maxwellian Averaged Cross Section at kT = 5 keV by about a factor of two with respect to the value assumed so far. In 206Pb we have determined capture cross sections for a large number (97) of resonances, which were not reported in the two previous capture measurements. We discuss preliminary implications of the new cross sections in the stellar nucleosynthesis of the Pb isotopes.
