The neutron charge form factor in helium-3

Abstract

In order to measure the charge form factor of the neutron, $G_E^n(Q^2)$, one needs to use a neutron bound in a nuclear target. We calculate the change in the form factor for a neutron bound in ${}^{3}He$, with respect to the free case, using several versions of the quark meson coupling model. It is found that the form factor may be suppressed by as much as 12% at $Q^2=0.5{GeV}^2$ with respect to that of the free neutron.
