The reaction ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$(e,e’d${)}^4$He, carried out with quasifree kinematics, is ideally suited for mapping out the ${}_{}{}^6{}_{}{}^{}\to \mathit{\alpha }+\mathrm{d}$ momentum distribution in the region where Pauli effects from the underlying $S_{1/2}$ αN interaction are manifest. Data for the ${}_{}{}^6{}_{}{}^{}\to \mathit{\alpha }+\mathrm{d}$ momentum distribution in the range of alpha-particle recoil momenta of 0.0 to 1.4 ${\mathrm{fm}}^{\mathrm{-}1}$ are important to understanding three-body models of ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ in general and the $S_{1/2}$ αN interaction in particular. In anticipation of ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$(e,e’d${)}^4$He coincidence measurements, the cross section is calculated with three-body models of ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ under the assumptions of one-photon exchange and deuteron-pole dominance. The required kinematical conditions that make the theory applicable are emphasized.
