(a New Proposal to Jeeerson Lab Pac18) Measurement of Neutron ( 3 He) Spin Structure Functions in the Resonance Region
نویسندگان
چکیده
We propose a precision extraction of the neutron spin structure function g 1 and the virtual photon asymmetry An1 in the resonance region over a moderate Q 2 range (up to Q = 4:2(GeV=c)) using a polarized He target. The Bloom-Gilman duality has been experimentally demonstrated for the spin independent structure functions down to small values of Q. The proposed experiment combined with Deep-Inelastic-Scattering data will provide a precision test of quark-hadron duality predictions for spin structure functions. The demonstration of duality for spin structure functions will enable the use of resonance data as a powerful tool to study the nucleon spin structure in the very high x region.

We propose to make a measurement of the spin-dependent scattering cross section for a longitudinally polarized electron beam off a transversely and longitudinally polarized He target. The measurement will cover excitation energies across the resonance and deep inelastic regions at constant 4-momentum transfer Q = 2 (GeV/c). We will extract the linear combination 2g1 + 3g2 of spin structure func...

I will discuss recent results from Jefferson Lab on the measurement of inclusive spin structure functions in the nucleon resonance region using polarized ammonia NH3 and polarized He targets. Preliminary results on the first moment of g1(x,Q ) for protons, and the generalized Gerasimov-Drell-Hearn integral for neutrons are presented. In addition, first double polarization data on exclusive elec...
متن کاملNew Results on Nucleon Spin Structure
Recent precision spin structure data from Jefferson Lab have significantly advanced our knowledge of nucleon structure in the valence quark (high-x) region and improved our understanding of higher-twist effects, spin sum rules and quark-hadron duality. First, results of a precision measurement of the neutron spin asymmetry, A 1 , in the high-x region are discussed. The new data shows clearly, f...
متن کاملNucleon and Nuclear Spin Structure Functions
Nuclear effects in polarized inelastic electron scattering off polarized He and polarized H are discussed; in the resonance region, Fermi motion effects are found to be much larger than in deep inelastic scattering. It is shown that improperly describing nuclear dynamics would lead to the extraction of unreliable neutron spin structure functions; on the other hand side, simple and workable equa...

Jefferson Lab experiment E01-012 measured the 3He spin-structure functions and virtual photon asymmetries in the resonance region in the momentum transfer range 1.0<Q2<4.0 (GeV/c)2. Our data, when compared with existing deep inelastic scattering data, were used to test quark-hadron duality in g1 and A1 for 3He and the neutron. In addition, preliminary results on the 3He spin-structure function ...
