Gamma production cross sections for neutron inelastic scattering reactions (n,xn) (x = 1,2,3) were measured for three different highly enriched targets of 206Pb, 207Pb and 208Pb and for 209Bi. Using the known decay schemes of these isotopes, the total inelastic cross sections and level inelastic cross sections were determined. The measurements are continuous in neutron energy and cover a wide interval (from threshold energy up to about 20 MeV). The experiments were performed at the GELINA white neutron source, at the 200 m flight path station with a time resolution of 8 ns, resulting in an unprecedented neutron energy resolution of 1.1 keV at 1 MeV (36 keV at 10 MeV).
