With the limited kinematic coverage of these experiments,
it has been impossible to disentangle which aspects of the theoretical description are problematic. While resolving these problems is interesting from a purely few-body physics point of view, it is also of critical importance to our interpretation of deep-inelastic
data from polarized <sup>3</sup>He which is often used as an effective polarized neutron target. A new idea to measure these reactions in CLAS12 with a new meta-stability exchange optical pumped
<sup>3</sup>He target. This new data, which will cover an extremely board range of kinematics, should allow determination of which model ingredients such as non-relativistic approach, choice of the NN force, relevance of the three-nucleon force, final-state
interactions, and/or meson-exchange currents need to be improved.</span></p>
