Abstract
The neutron scattering length of lead isotopes 204Pb, 207Pb and208Pb are determined by a set of neutron interferometry experiments. The obtained values b(208) = 9.494(30)fm, b(207) = 9.286(16)fm, b(204) = 10.893(78)fm have much higher accuracy then current table data. Together with the precise value of b for natural lead, these results represent a complete set of data and allow one to calculate b(206) = 9.221(69)fm, which is in the very good agreement with the present day experimental value.
