Resonant Spin Structure (RSS) of the Proton

Spin-dependent structure functions have been extracted from an inclusive doubly polarized asymmetry measurement at low momentum transfer ($Q^2\approx1.3 $GeV$^2$) in the resonance region. Longitudinally polarized electrons of incident energy 5.755 GeV were scattered from a polarized solid ammonia target in Jefferson Lab's experimental Hall C. Both NH$_3$ and ND$_3$ were used as target material giving access to the proton and deuteron spin structure respectively. For the first time at low $Q^2$ and in the resonance region, proton asymmetries were measured with both perpendicular and parallel target field orientation, allowing a precision determination of the spin structure functions g$_1$($x$,Q$^2$) and g$_2$($x$,Q$^2$). The $W-$dependence of the nucleon spin asymmetries $A_1(W,Q^2)$ and $A_2(W,Q^2)$ has been measured with high resolution, allowing for clear identification of individual resonance regions. Preliminary proton data will be presented which enable a test of local duality in the polarized structure functions. The moments of the spin structure functions, including the extended GDH sum and the $d_2$ matrix element, are also evaluated and compared with theoretical expectations.
