Study of the polarized structure functions of the neutron at low Q2 using polarized 3He

We have measured the electron-He-3 longitudinal and transverse spin dependent inclusive cross sections He-3( e,e') in the resonance region over a range of four-momentum transfer from 0.1 to 0.9 GeV2. From this measurement, the spin dependent structure functions g(1)(x), g(2)(x) of He-3 have been extracted and various moments of the neutron were evaluated. The integral of g(1)(x) shows a smooth continuation from the existing high Q(2) data toward Q(2) similar to 0. And that of g(2)(x) provided the first significant experimental evidence of the Burkhardt-Cottingham Sum Rule on the neutron in our measured Q(2) region. Spin polarizabilities of the neutron (gamma(0) and delta(LT)) were evaluated and compared with the existing chiral perturbation calculations and MAID model. Higher twist effect on g(2)(x) was studied from d(2) moments and finally, color polarizabilities of the neutron were extracted from the combined data of the world and Jefferson Lab. Our new results seem to show small higher twist effects in the neutron with a possibility of quark-hadron duality down to Q(2) similar to 0.5 GeV2.
