Probing $^{3}$He and $^{3}$H in the Quasi-Elastic Regime*

Quasi-elastic electron scattering was used to probe nucleons on the nucleus of the mirror $^{3}$He and $^{3}$H nuclei, in a Q$^{2}$ range of 0.5-3GeV$^{2}$/c$^{2}$ in Hall A at Jefferson Lab. The unique sealed gas targets contained 53.37 mg/cm$^{2}$ and 85.1 mg/cm$^{2}$ of $^{3}$He and $^{3}$H, respectively. The beam energies were 2.2 GeV and 4.3 GeV, with a maximum current of 22 $\mu$A. This talk presents the details of the physics analysis and the preliminary results of the $^{3}$He(e,e') and $^{3}$H(e,e') data and how it can be used to learn about the magnetic form factor of the neutron.
