Neutron charge radius and the new experiments proposed for the precise (n,e)-scattering length measurement

摘要

Relationship between the n,e-scattering length, b(sub ne), and the neutron mean square charge radius and anomalous magnetic moment (mu)(sub n), the quantities which characterize the internal structure of the neutron, was investigated. The performed analysis showed that in the framework of the modern cloudy bag model (CBM) of the nucleon the value of b(sub ne) is determined by the value of without the so-called Foldy term being taken into account, while in the framework of the phenomenological Foldy approach the experimental values of b(sub ne) obtained up to date can be described only by this Foldy term within an accuracy of about 10%, i.e., by the anomalous magnetic moment of the neutron (mu)(sub n). Then a necessity is obvious to obtain b(sub ne) estimates, new experiments to measure the energy dependence of the slow neutron scattering cross section by (sup 86)Kr and scattering anisotropy on Xe isotopes, have been proposed. 18 refs., 4 figs., 1 tab.
