Using experimental data from the neutron transmission measurements on enriched 206,207,208Pb, natural Pb and Bi targets, the potential scattering radii R' and the electric polarizability of the neutron αn were determined by general least squares fit at fixed neutron-electron bound scattering length values: bne = −1.32 × 10−3 fm (Garching) and bne = −1.59 × 10−3 fm (Dubna). The evaluations were performed in two versions: (1) The potential scattering radii R' were taken as fitted parameters; (2) R' values were deduced from optical model calculations. The obtained potential scattering radii values are in the range R' = 9.0 − 10.0 fm. The electric polarizability of the neutron in the first version resulted in αn = +(0.12 ± 0.44) × 10−3 fm3 with the Garching bne value and αn = −(0.97 ± 0.44) × 10−3 fm3 with the Dubna bne value, but in the second calculation version - in αn = −(0.14 ± 0.37) × 10−3 fm3 with both bne values. On the basis of obtained results we give preference to the Garching bne value.
