Analyzing power measurements for both inclusive $\left(\overrightarrow{p}{,p}^{\prime }\right)$ and exclusive $(\overrightarrow{p},2p)$ and $(\overrightarrow{p},np)$ quasifree scattering at 200 MeV from ${}^2\mathrm{H}$ and ${}^{12}\mathrm{C}$ have been completed in the angular range from 27° to 34°. Previous experimental and theoretical work has indicated non-negligible suppression of the inclusive $\left(\overrightarrow{p}{,p}^{\prime }\right)$ analyzing powers with respect to impulse approximation calculations. Conversely, both suppression and enhancement of the isovector $(\overrightarrow{p},n)$ analyzing power data have been found depending on the mass number of the target. Both nonrelativistic and fully relativistic calculations have sought to explain these features. However to address such questions within the inclusive data, it is important to fully understand the makeup of the inclusive spectra. This ensures that any “nonconventional” aspects of the data do not arise from contamination of the quasifree scattering yield.
