Neutron charge form factor at large $q^2$

The neutron charge form factor $G_{\mathrm{En}}\mathrm{}\left(q\right)\mathrm{}$ is determined from an analysis of the deuteron quadrupole form factor $F_{C2\mathrm{}}\mathrm{}\left(q\right)\mathrm{}$ data. Recent calculations, based on a variety of different model interactions and currents, indicate that the contributions associated with the uncertain two-body operators of shorter range are relatively small for $F_{C2\mathrm{}}\mathrm{}\left(q\right),$ even at large momentum transfer q. Hence, $G_{\mathrm{En}}\mathrm{}\left(q\right)\mathrm{}$ can be extracted from $F_{C2\mathrm{}}\mathrm{}\left(q\right)\mathrm{}$ at large $q^2$ without undue systematic uncertainties from theory.
