Moments of the neutron g2 structure function at intermediate Q2

Journal Article (Journal Article)

We present new experimental results for the He3 spin structure function g2 in the resonance region at Q2 values between 1.2 and 3.0(GeV/c)2. Spin dependent moments of the neutron were extracted. Our main result, the inelastic contribution to the neutron d2 matrix element, was found to be small at (Q2)=2.4(GeV/c)2 and in agreement with the lattice QCD calculation. The Burkhardt-Cottingham sum rule for He3 and the neutron was tested with the measured data and using the Wandzura-Wilczek relation for the low x unmeasured region.
