Inclusive scattering of polarized electrons on polarized ${}^3\mathrm{He}:$ Effects of final state interaction and the magnetic form factor of the neutron

Effects of final state interaction on asymmetries in inclusive scattering of polarized electrons on polarized ${}^3\mathrm{He}$ are investigated using a consistent ${}^3\mathrm{He}$ bound state wave function and $3N$ continuum scattering states. Significant effects are found, which influence the extraction of the magnetic neutron form factor from $A_{T^{\prime }}.$ The enhancement found experimentally for $A_{{\mathrm{TL}}^{\prime }}$ near the $3N$ breakup threshold, which could not be explained in calculations carried through in plane wave impulse approximation up to now, occurs now also in theory if the full final state interaction is included.
