The spin-structure functions and , and the spin-dependent partial cross-section have been extracted from the polarized cross-sections differences, and measured for the 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 and 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 , and are evaluated with high precision for the neutron in the range from 0.035 to . 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.
