Measurement of the Spin Structure Function of the Neutron G1(N) from Deep Inelastic Scattering of Polarized Electrons from Polarized Neutrons in He-3
- SLAC
Polarized electrons of energies 19.42, 22.67, and 25.5 GeV were scattered off a polarized {sup 3}He target at SLAC's End Station A to measure the spin asymmetry of the neutron. From this asymmetry, the spin dependent structure function g{sub 1}{sup n}(x) was determined over a range in x from 0.03 to 0.6 with an average Q{sup 2} of 2 (GeV/C){sup 2}. The value of the integral of g{sub 1}{sup n} over x is {integral}g{sub 1}{sup n}(x)dx = -0.036 {+-} 0.009. The results were interpreted in the frame work of the Quark Parton Model (QPM) and used to test the Ellis-Jaffe and Bjorken sum rules. The value of the integral is 2.6 standard deviations from the Ellis-Jaffe prediction while the Bjorken sum rule was found to be in agreement with this data and proton data from SMC and E-143.
