Abstract
We present a detailed analysis of nuclear effects in inclusive electron scattering from polarized ${}^{3}$He nuclei for polarization asymmetries, structure functions, and their moments, in both the nucleon-resonance and deep-inelastic regions. We compare the results of calculations within the weak binding approximation at finite ${Q}^{2}$ with the effective polarization ansatz often used in experimental data analyses and explore the impact of $\ensuremath{\Delta}$ components in the nuclear wave function and nucleon off-shell corrections on extractions of the free neutron structure. Using the same framework we also make predictions for the ${Q}^{2}$ dependence of quasielastic scattering from polarized ${}^{3}$He, data which can be used to constrain the spin-dependent nuclear smearing functions in ${}^{3}$He.
