Measurement of charged pion asymmetries in scattering of polarized electrons from polarizedHe3

It is proposed that a measurement of the ratio of the charged pion asymmetries for the Δ(1232) resonance with a polarized electron beam on a polarized ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ target provides a sensitive test of the presence of Δ components in the ground state of ${}_{}{}^3{}_{}{}^{}\mathrm{He}$. In the absence of final-state interactions and nonresonant contributions, it is estimated in a simple quasielastic scattering picture that the ratio of charged pion asymmetries would change by a factor of 2 for a 2% probability to find a Δ in the ground state of ${}_{}{}^3{}_{}{}^{}\mathrm{He}$.
