Gamma-ray transitions following neutron capture in 206Pb have been studied at the cold neutron beam facility of the Budapest Neutron Centre using a metallic sample enriched in 206Pb and a natural lead nitrate powder pellet. The measurements were performed using a coaxial HPGe detector with Compton suppression. The observed gamma-rays have been incorporated into a decay scheme for neutron capture in 206Pb. Partial capture cross sections for 206Pb(n,g) at thermal energy have been derived relative to the cross section for the 1884 keV transition after neutron capture in 14N. From the average crossing sum a total thermal neutron capture cross section of 29+2-1 mb was derived for the 206Pb(n,g) reaction. The thermal neutron capture cross section for 206Pb has been compared with contributions due to both direct capture and distant unbound s-wave resonances. From the same measurements a thermal neutron induced capture cross section of (649 +/- 14) mb was determined for the 207Pb(n,g) reaction.
