Abstract
The value of the neutron mean square intrinsic charge radius (MSICR) [ r(in)(2)](N) is discussed. The experimental data table of the n-e scat tering length values alpha(ne) is presented. The experiments can be di vided into two groups [r(in)(2)](N) > 0 and [r(in)(2)](N). A possible reason for the discrepancy between the results of the Garching (German y) and Dubna (Russia) determination of alpha(ne) by the transmission m ethod is discussed. It is shown that introduction into sigma(tot) of e nergy-independent interresonance interference terms does not affect th e result obtained in Dubna. The results of [r(in)(2)](N) > 0 are in co ntradiction with modern theory and the results of [r(in)(2)](N) < 0 ar e in confirmation of modern theory.
