We discuss the experimental data on the n,e-scattering length bne and thevalues of mean square charge radius of the neutron <r^2> obtained from them. Itis shown that the accumulated during the last 50 years most significantexperimental estimates of the bne are not contradictory and lead to the averagevalue <r^2>=-0.1178+-0.0037 fm^2. Assuming that all the authors haveunderestimated the errors of their measurements by a factor of 1.7, thecombined fit of all available experimental data would lead to Chi^2~1 perdegree of freedom. Different modern theoretical predictions of <r^2> areconsidered. They are found to be in a good agreement with the obtainedexperimental value <r^2>. However the existing theoretical description of thestructure of neutron does not provide a value of <r^2> with a sufficientaccuracy.

Comments to the problem of experimental determination of the neutron-electron scattering length and its theoretical interpretation
