Comparative study of nuclear effects in polarized electron scattering from 3He

Abstract

We present a detailed analysis of nuclear effects in inclusive electron scattering from polarized 3He nuclei for polarization asymmetries, structure functions and their moments, both in 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 Δ 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 3He, data on which can be used to constrain the spin-dependent nuclear smearing functions in 3He.
