   Abstract:
   The spin-structure functions g1 and g2, and the spin-dependent partial cross-section σTT have been extracted from the polarized cross-sections differences, Δσ∥(ν,Q²) and Δσ⊥(ν,Q²) measured for the He3→(e→,e^′)X reaction, in the E97-110 experiment at Jefferson Lab. Polarized electrons with energies from 1.147 to 4.404 GeV were scattered at angles of 6^∘ and 9^∘ from a longitudinally or transversely polarized ³He target. The data cover the kinematic regions of the quasi-elastic, resonance production and beyond. From the extracted spin-structure functions, the first moments Γ1‾(Q²), Γ2(Q²) and ITT(Q²) are evaluated with high precision for the neutron in the Q² range from 0.035 to 0.24GeV². The comparison of the data and the chiral effective field theory predictions reveals the importance of proper treatment of the Δ degree of freedom for spin observables.
