Abstract
The neutron scattering length of lead isotopes (204)pb, Pb-207 and Pb-208 a re 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 th e very good agreement with the present day experimental value.
